Sustainable Jewelry Materials Comparison: What to Choose and Why

A sustainable jewelry materials comparison should answer a practical question: which material gives you the right mix of beauty, durability, ethics, and price for a specific piece, such as a 1.2ct F-VS2 round brilliant lab-grown Diamond Engagement Ring in 14K white gold versus a 6mm 950 platinum wedding band. The right answer changes by use case because a daily-wear cathedral setting with a pave band faces different wear than a sterling silver 18-inch necklace or a plain comfort-fit band.

Most shoppers compare lab-grown diamonds, recycled 14K and 18K gold, recycled 950 platinum, moissanite, and traceable colored gemstones such as Sri Lankan sapphire or Montana sapphire. These choices can all support more responsible jewelry buying, but each one has trade-offs in hardness, certification, care, and price; the strongest option is often a smart pairing, such as an IGI-certified 1.0ct E-VS1 lab-grown diamond set in recycled 14K yellow gold.

I have helped many couples compare sustainable jewelry options, and the conversation usually comes back to three measurable details: whether the stone has strong cut performance, whether the sourcing is supported by a GIA, IGI, or GCAL report, and whether the piece will hold up to daily wear in a secure setting such as a six-prong solitaire or bezel setting. That instinct is sound because fine jewelry should feel good to buy and still look crisp after years of cleaning, resizing, and routine prong inspections.

Sustainable Jewelry Materials Comparison: The Main Factors

A useful sustainable jewelry materials comparison looks beyond broad green claims and checks origin, proof, wearability, repair options, and total cost for materials such as 14K recycled gold, 18K recycled gold, 950 platinum, and lab-grown diamonds graded by GIA, IGI, or GCAL. If a seller cannot explain where the stone or metal came from, the sustainability claim is weak even if the ring features a high-value center stone such as a 1.5ct F-VS2 oval lab-grown diamond.

Here are the factors worth weighing Before You Buy a piece such as a 1ct lab-grown diamond solitaire in recycled 14K white gold or a 3mm recycled platinum wedding band:

1. Environmental impact: mining disturbance, energy use, water use, refining waste, and the production method for CVD or HPHT lab-grown diamonds.
2. Responsible sourcing: traceable supply chains, GIA, IGI, or GCAL grading reports, recycled metal declarations, and supplier standards.
3. Durability: Mohs hardness, toughness, scratch resistance, prong security, and daily-wear fit for settings such as bezel, cathedral, solitaire, and pave.
4. Value: purchase price, repair cost, resizing cost, metal value, and likely resale demand for lab-grown diamonds, moissanite, gold, and platinum.
5. Appearance: diamond cut quality, color grade, clarity grade, metal tone, rhodium plating on 14K white gold, and design flexibility.

Numbers help because diamonds rate 10 on the Mohs hardness scale, moissanite rates about 9.25, sapphire and ruby rate 9, and emerald usually rates 7.5 to 8 with more vulnerability from inclusions. Standard sterling silver is 92.5% silver, 14K gold is 58.3% gold, 18K gold is 75% gold, and fine jewelry platinum is often 950 platinum, meaning 95% pure platinum with 5% alloy metal for strength.

For engagement rings, a sustainable jewelry materials comparison often favors lab-grown diamonds with recycled 14K gold or 950 platinum, especially for daily-wear designs like a 1.2ct F-VS2 round brilliant in a cathedral setting with a pave band. For wedding bands, recycled precious metals usually carry the most weight, while everyday jewelry can use moissanite, recycled sterling silver, and traceable colored gemstones for strong style at lower price points.

Lab-Grown Diamonds: Best for Classic Sparkle With Clearer Origin

Lab-grown diamonds are real diamonds made in controlled production settings using CVD or HPHT growth, and they have the same carbon crystal structure as mined diamonds. They also share diamond's Mohs 10 hardness, which makes a 1.0ct F-VS2 round brilliant lab-grown diamond a practical choice for engagement rings, stud earrings, tennis bracelets, and solitaire pendants.

The biggest buyer benefit is diamond brilliance and diamond durability without the same mining footprint tied to newly extracted stones, especially when the diamond is paired with recycled 14K yellow gold, 14K white gold, 18K rose gold, or 950 platinum. In a sustainable jewelry materials comparison, lab-grown diamonds work especially well for shoppers who want a traditional look, a GIA, IGI, or GCAL report, and a clearer sourcing path.

How Lab-Grown Diamonds Compare With Mined Diamonds

A well-cut lab-grown diamond can look identical to a mined diamond of the same grade, such as a 1.2ct F-VS2 round brilliant with Excellent cut, Excellent polish, and Excellent symmetry. Cut quality drives sparkle more than origin does, so a poorly cut 1.5ct stone with a deep pavilion can look flat whether it came from a lab or the ground.

GIA, IGI, and GCAL grade lab-grown diamonds, and their reports help buyers compare the 4Cs: cut, color, clarity, and carat weight. GIA states that laboratory-grown diamonds have essentially the same chemical, optical, and physical properties as natural diamonds, while IGI and GCAL reports often include helpful details such as measurements, growth method disclosure, and laser inscription numbers.

The difference sits in origin, price, and resale behavior because a 1ct lab-grown diamond commonly falls around $2,800-$4,200 in fine jewelry retail depending on cut, color, clarity, shape, and setting choice, while a comparable mined diamond often costs more. Resale markets for lab-grown stones are still developing, so buyers should treat a 1.0ct E-VS1 lab-grown diamond as a beauty, durability, and ethics choice rather than a guaranteed investment.

Lab-grown diamonds make the most sense when you want the emotion and sparkle people expect from a proposal ring while using the budget for better specs, such as moving from a 0.80ct G-SI1 mined diamond to a 1.2ct F-VS2 lab-grown diamond with Excellent cut. The savings can also support a more thoughtful setting, such as a hidden-halo cathedral ring in recycled 14K white gold or a low-profile bezel setting in 950 platinum.

What to Ask Before Buying a Lab-Grown Diamond

Ask for the grading report first, then check the cut grade, measurements, table percentage, depth percentage, polish, symmetry, fluorescence, and whether the seller clearly discloses that the stone is lab-grown. If energy use matters to you, ask where the CVD or HPHT diamond was grown and whether the producer shares details about power sources, emissions data, or third-party verification.

Do not rely on the phrase "carbon neutral" by itself because it can mean the producer offsets emissions rather than reducing them at the source. A stronger claim will explain the diamond production method, energy mix, verification standard, and report details for a specific stone, such as an IGI-certified 1.31ct D-VVS2 oval lab-grown diamond with a laser inscription on the girdle.

Pros:

• Same Mohs 10 diamond hardness and diamond brilliance as mined diamonds.
• Strong choice for engagement rings, daily-wear studs, tennis bracelets, and pendants.
• Often lower price than mined diamonds of similar grade, with many 1ct lab-grown diamonds retailing around $2,800-$4,200 depending on specs.
• Often easier to trace through GIA, IGI, or GCAL documentation and seller disclosure.
• Works well with recycled 14K gold, recycled 18K gold, or recycled 950 platinum.

Cons:

• Resale value can be less predictable than mined diamonds or precious metal value.
• Quality still varies by cut, CVD or HPHT growth, post-growth treatment, and finishing.
• Energy claims need proof beyond a general sustainability statement.
• Some buyers prefer natural-origin stones for personal, family, or heirloom reasons.

For many shoppers, the best sustainable jewelry materials comparison starts with a lab-grown diamond because it gives the expected fine-jewelry look with measurable specs such as carat weight, color grade, clarity grade, cut grade, and certification number. A 1.2ct F-VS2 round brilliant lab-grown diamond in recycled 14K white gold is often easier to compare, insure, and maintain than a gemstone with unclear treatment history.

Recycled Precious Metals: The Quiet Strength in Eco-Friendly Jewelry

Recycled gold, recycled platinum, and recycled silver are recovered from existing metal sources such as old jewelry, refining scrap, industrial material, and post-consumer precious metal. After refining, the metal can meet the same purity standards as newly mined metal, meaning recycled 14K gold still contains 58.3% gold and recycled 950 platinum still contains 95% platinum.

That matters because precious metal mining can require heavy land use, energy, water, and waste management, while recycled metal reduces demand for new extraction. In a sustainable jewelry materials comparison, recycled metal is often the easiest responsible upgrade because it performs like newly mined 14K white gold, 18K yellow gold, 18K rose gold, sterling silver, or 950 platinum in the finished setting.

Recycled Gold, Platinum, and Silver

Recycled gold can be made into yellow, white, or rose gold for Engagement Ring Settings, wedding bands, chains, earrings, and bracelets. The recycled source does not change the karat, so a 14K recycled gold cathedral setting is still 58.3% gold, while an 18K recycled gold solitaire setting is still 75% gold and has a richer yellow tone.

Recycled platinum is a premium white metal with high density and excellent wear resistance, especially in daily-wear pieces such as shared-prong bands, bezel settings, and three-stone engagement rings. Many platinum rings use 950 platinum, which means the alloy is 95% platinum and offers strong prong security for stones like a 1.5ct elongated cushion lab-grown diamond.

Recycled silver is more affordable and works well for everyday jewelry such as 925 sterling silver hoops, signet rings, pendants, and chain bracelets. Sterling silver is usually 92.5% silver mixed with 7.5% alloy metal for strength, and it can tarnish from sulfur exposure, lotion, chlorine, and humidity unless it is polished with a silver cloth or stored in an anti-tarnish pouch.

How to Verify Recycled Metal Claims

Ask whether the metal is fully recycled, partially recycled, or blended, and request refinery documentation, supplier declarations, or chain-of-custody support for 14K gold, 18K gold, 925 silver, or 950 platinum. A clear answer should identify the recycled metal content instead of relying on vague wording such as "responsibly made" for a ring that may include only partial recycled material.

Recycled metal does not automatically make an entire piece sustainable because the center stone, melee diamonds, setting process, packaging, repair policy, and manufacturing waste also matter. Still, a recycled 14K gold or 950 platinum setting gives buyers a strong base for responsible sourcing, especially when paired with an IGI-certified lab-grown diamond or a traceable sapphire.

Pros:

• Reduces demand for newly mined precious metals such as gold, platinum, and silver.
• Performs like newly mined 14K gold, 18K gold, 925 sterling silver, or 950 platinum.
• Fits classic and modern jewelry designs, including solitaire, cathedral, bezel, halo, and pave settings.
• Pairs well with lab-grown diamonds, moissanite, sapphire, ruby, and other colored stones.
• Often easy to maintain and repair through polishing, rhodium plating, resizing, and prong retipping.

Cons:

• Documentation quality varies by seller, refinery, and supplier chain.
• Some jewelry uses only partial recycled content in the alloy or setting components.
• The gemstone may still have unclear sourcing, treatment, or origin.
• Premium metals such as 950 platinum can cost more upfront than 14K gold.

If you want a practical win, choose recycled metal for the setting, such as recycled 14K yellow gold for warmth, recycled 14K white gold with rhodium plating for a bright white look, or recycled 950 platinum for dense prong security. This strengthens a sustainable jewelry materials comparison without forcing you into a narrow design style.

Moissanite and Ethical Gemstones: Smart Alternatives to Diamonds

Lab-grown diamonds and recycled metals are not the only responsible choices because moissanite, lab-created sapphire, traceable natural sapphire, and ethically sourced colored gemstones can also make sense. These options are especially useful when you want more visible size, more color, or a different price point than a 1ct lab-grown diamond in 14K gold.

Moissanite

Moissanite is a popular diamond alternative with strong sparkle, a refractive index of about 2.65-2.69, and a Mohs hardness of about 9.25. It is durable enough for many engagement rings and everyday pieces, and a 1ct diamond-equivalent moissanite often costs far less than a 1ct lab-grown diamond or mined diamond.

Moissanite has a different look from diamond because it can show more rainbow fire, especially in bright light and larger sizes such as 8mm round or 10x8mm oval stones. Some shoppers love that extra flash, while others prefer the crisper white brilliance of a GIA, IGI, or GCAL-graded diamond.

In a sustainable jewelry materials comparison, moissanite works well for buyers who want impact, durability, and lower cost in settings such as a bezel solitaire, hidden-halo cathedral setting, or three-stone ring. The trade-off is resale demand because moissanite usually does not carry the same secondary-market interest as diamonds, 14K gold, 18K gold, or 950 platinum.

The best stone is not always the one with the most traditional prestige because a 7.5mm round moissanite in recycled 14K yellow gold can give a bold engagement-ring look at a much lower price than a 1.5ct diamond. If your partner loves strong rainbow fire and you want room in the budget for the wedding, honeymoon, or home, moissanite can be a thoughtful choice even in a daily-wear cathedral or bezel setting.

Ethical Colored Gemstones

Sapphires, rubies, emeralds, spinel, aquamarine, and garnet can all support responsible jewelry design when sourcing, treatment, and durability are clear. A blue sapphire engagement ring, such as a 1.5ct oval Sri Lankan sapphire in recycled 18K yellow gold, can feel classic without looking expected.

Quality checks matter more with colored gemstones because treatments vary widely, especially with heated sapphire, fracture-filled ruby, oil-treated emerald, dyed stones, and coated gems. Ask whether the stone is heated, filled, dyed, coated, irradiated, or untreated, and request a GIA, AGL, GRS, or other recognized gem lab report when the gemstone value justifies it.

Durability also varies because sapphire and ruby rate 9 on the Mohs scale, spinel rates about 8, aquamarine rates 7.5-8, and emerald rates 7.5-8 but often contains inclusions and oil treatment. For rings, sapphire and ruby usually handle daily wear better than emerald, while emerald is often safer in earrings, pendants, or protective bezel settings.

Other Lower-Impact Materials

Some jewelry uses lab-created colored stones, recycled glass, reclaimed wood, ceramic, titanium, or bio-based materials for fashion jewelry and gifts. These materials can be attractive, but they usually do not match the long-term wear profile of 14K gold, 18K gold, 950 platinum, diamond, moissanite, ruby, or sapphire.

Use these materials for style-first pieces rather than daily-wear heirlooms, especially when the item is a ring exposed to water, impact, and abrasion. If you will wear a ring every day, prioritize hardness, setting security, and repair options because soft-stone rings under Mohs 7 can show scratches or chips much sooner than a diamond, sapphire, or moissanite ring.

Sustainable Jewelry Materials Comparison Chart

Use this chart as a quick reference before you choose a stone or setting, whether you are comparing a 1ct lab-grown diamond in 14K white gold, a moissanite solitaire in 14K yellow gold, or a 950 platinum wedding band.

Material	Environmental Profile	Sourcing Strength	Durability	Appearance	Price Position	Best Proof to Request
Lab-grown diamond	Lower mining impact; CVD or HPHT energy use varies by producer	Strong with lab report, laser inscription, and lab-grown origin disclosure	Excellent, Mohs 10	Classic diamond brilliance in round, oval, cushion, emerald, and pear cuts	Often $2,800-$4,200 for a 1ct fine-jewelry ring depending on specs and setting	GIA, IGI, or GCAL grading report
Recycled gold	Reduces demand for new gold mining and refining	Strong with refinery documents or supplier recycled-content statement	Excellent for daily wear in 14K or 18K alloys	Yellow, white, or rose gold; 14K white gold often rhodium plated	Similar to standard gold at the same karat and weight	Recycled content statement and 14K or 18K purity mark
Recycled platinum	Reduces demand for new platinum mining	Strong with chain-of-custody support	Excellent; dense, secure, and commonly 950 platinum	Premium naturally white metal with substantial feel	Higher upfront cost than many 14K gold settings	Supplier or refinery documentation and 950 platinum stamp
Recycled silver	Lower-cost recycled precious metal option	Good with clear supplier claim	Good, but softer than gold or platinum; 925 sterling can tarnish	Bright white metal suited to earrings, pendants, and casual rings	Affordable compared with gold or platinum	925 sterling mark and recycled sourcing claim
Moissanite	Avoids diamond mining and is commonly lab-created	Strong with clear lab-created disclosure	Very good, Mohs 9.25	Bright rainbow fire, especially in larger round and oval cuts	Lower than diamond at similar visible size	Product disclosure, brand warranty, or lab report
Ethical colored gemstone	Varies by mine, country of origin, treatment, and cutting practices	Strong only with origin and treatment transparency	Varies by species; sapphire and ruby are Mohs 9	Rich color and character in sapphire, ruby, emerald, spinel, and garnet	Wide range based on species, origin, treatment, and size	Origin, treatment disclosure, and GIA, AGL, or other gem lab report

For engagement rings, lab-grown diamonds set in recycled 14K gold or 950 platinum offer the best overall balance of Mohs 10 durability, visible brilliance, traceable certification, and cost control. For wedding bands, recycled metal usually wins because the metal is the main material, while moissanite and ethical colored gemstones give statement pieces more creative range.

A simple rule is to match the material to the way you will wear the jewelry: daily rings need hardness, secure prongs, and repairability, while occasional earrings and pendants can take more creative risks. A 1.0ct lab-grown diamond solitaire, a 6mm recycled platinum band, and an emerald pendant each need different standards for impact resistance, cleaning, and long-term maintenance.

How to Choose the Right Sustainable Jewelry Material

A sustainable jewelry materials comparison should end with a choice, not a longer list of maybes, so start with the piece type and then weigh style, budget, sourcing, and care. A daily-wear engagement ring may call for a 1.2ct F-VS2 lab-grown diamond in a six-prong 14K white gold setting, while a lower-contact pendant can feature a more delicate gemstone such as emerald or aquamarine.

If You Want a Classic Engagement Ring

Choose a lab-grown diamond with a GIA, IGI, or GCAL report, then set it in recycled 14K gold, recycled 18K gold, or recycled 950 platinum. This pairing gives you diamond durability, familiar beauty, and stronger traceability, and you can compare options in StoneBridge Jewelry's lab-grown diamond collection or start with a setting in the engagement rings collection.

Couples often relax once they see this combination side by side: a bright 1.2ct F-VS2 round brilliant lab-grown diamond, a recycled 14K white gold cathedral setting, and a design with practical details like a secure six-prong head or low-profile basket. A proposal ring carries a lot of emotion, and precise materials should support that feeling instead of adding stress.

If You Want the Best Value

Moissanite gives you a larger look for less money, especially in sizes like 7.5mm round, 8x6mm oval, or 9x7mm cushion stones. Recycled sterling silver can work for lower-cost everyday jewelry, though it needs more tarnish care than 14K gold or 950 platinum, while lab-grown diamonds often stretch the budget further than mined diamonds when you want a true diamond with a GIA, IGI, or GCAL report.

If Ethics Matter Most

Prioritize documentation such as GIA, IGI, or GCAL grading reports, recycled metal statements, and treatment disclosures for sapphires, rubies, emeralds, and other colored stones. A seller should be able to explain whether a 1.0ct E-VS1 diamond is lab-grown, whether a 14K white gold setting uses recycled alloy, and whether a sapphire is heated or untreated.

If Long-Term Material Value Matters

Precious metals usually hold intrinsic value better than gem alternatives because 14K gold, 18K gold, and 950 platinum carry metal value independent of the center stone. Lab-grown diamonds can offer excellent beauty and ethical value, but resale expectations are different from mined diamonds, so buyers should separate emotional value, daily-wear durability, and secondary-market assumptions.

Before buying, use this checklist for a ring, pendant, bracelet, or pair of studs with specific specs such as a 1.2ct F-VS2 lab-grown diamond or a 3mm 14K yellow gold band:

1. Confirm the stone origin and ask for a GIA, IGI, GCAL, AGL, or other appropriate lab report when available.
2. Check the metal purity, such as 14K, 18K, 925 sterling silver, or 950 platinum.
3. Ask whether recycled metal content is documented by the supplier or refinery.
4. Review resizing, ultrasonic cleaning, steam cleaning, rhodium plating, warranty, and prong repair policies.
5. View the design in the actual carat size, millimeter size, or band width you plan to buy.

StoneBridge customers often use the ring builder to compare stone size, metal color, and setting style together, such as a 1.0ct oval lab-grown diamond in 14K rose gold versus a 1.5ct round lab-grown diamond in 950 platinum. Sustainability matters most when the finished piece still matches your daily routine, cleaning habits, and long-term repair needs.

Best Sustainable Jewelry Materials by Category

For engagement rings, the top recommendation is a lab-grown diamond in recycled 14K gold, recycled 18K gold, or recycled 950 platinum. It gives you the strongest mix of diamond brilliance, Mohs 10 durability, GIA, IGI, or GCAL sourcing clarity, and cost control, making it the clearest winner in a sustainable jewelry materials comparison for most bridal shoppers.

For wedding bands, choose recycled 14K gold, recycled 18K gold, or recycled 950 platinum because a band takes daily contact from desks, gym equipment, door handles, and handwashing. Platinum suits buyers who want a substantial naturally white 950 metal, while gold gives more color choices and usually a lower starting price for 2mm, 4mm, or 6mm bands.

For everyday jewelry, recycled 14K gold, recycled sterling silver, and moissanite are strong choices because they offer good wear, broad style range, and easier pricing. For personal gifts, traceable colored gemstones such as Montana sapphire, Australian sapphire, or lab-created ruby can make a 14K gold pendant or ring feel more specific and less predictable.

For fashion-forward designs, colored gemstones and alternative materials can shine, especially in earrings and pendants that face less impact than rings. Check hardness and treatment before choosing them for daily rings because a sapphire at Mohs 9 is much safer for an engagement ring than an opal at about Mohs 5.5-6.5.

For anniversary gifts, graduation gifts, or a "just because" piece, materials that carry a sourcing story without becoming fussy to wear tend to work best. A recycled 14K gold necklace, moissanite studs in 14K white gold, or a traceable 1.25ct sapphire ring in a bezel setting can feel considered, beautiful, and easy to maintain.

Care and Maintenance for Sustainable Jewelry Materials

Lab-grown diamonds are safe for most ultrasonic cleaners when the stone is intact and securely set, because a diamond's Mohs 10 hardness and stable crystal structure can handle standard jewelry cleaning. Avoid ultrasonic cleaning if the ring has fragile side stones, loose prongs, fracture-filled gemstones, or an antique-style setting with delicate pave, and schedule prong checks every 6-12 months for daily-wear engagement rings.

Moissanite is also generally safe in an ultrasonic cleaner when securely set, and it benefits from routine cleaning because lotion and soap can dull its high fire. Use warm water, mild dish soap, and a soft toothbrush for a 14K gold or platinum moissanite ring, then have a jeweler inspect prongs, bezels, and pave beads at least once a year.

Recycled 14K white gold may need rhodium replating every 12-24 months depending on wear, body chemistry, and how often the ring contacts hard surfaces. Recycled 18K yellow gold and 18K rose gold do not need rhodium, while 950 platinum develops a natural patina that can be polished or left as part of the metal's character.

Sterling silver jewelry should be stored in an anti-tarnish pouch and cleaned with a silver polishing cloth rather than harsh dips for pieces with gemstones or oxidized details. Avoid chlorine, bleach, and hot tubs with 925 silver, 14K gold, 18K gold, and platinum jewelry because chemicals can attack alloys, solder joints, and plated finishes.

FAQ: Sustainable Jewelry Materials Comparison

Are lab-grown diamonds more sustainable than mined diamonds?

Lab-grown diamonds often carry a lower mining impact because they do not require new diamond extraction, but CVD or HPHT energy use still matters. For the strongest sustainable jewelry materials comparison, look for GIA, IGI, or GCAL grading, clear lab-grown disclosure, and a recycled 14K gold or 950 platinum setting for a stone such as a 1.0ct F-VS2 round brilliant.

What is the most eco-friendly material for an engagement ring?

A lab-grown diamond set in recycled 14K gold, recycled 18K gold, or recycled 950 platinum is one of the strongest choices for an eco-friendly engagement ring. The diamond gives you Mohs 10 hardness, while the recycled metal reduces demand for new mining, and moissanite is also a smart option if you want more visible size than a 1ct diamond budget allows.

Is recycled gold as durable as newly mined gold?

Yes, recycled gold can be just as durable as newly mined gold when the alloy and craftsmanship are the same. A 14K recycled gold ring still contains 58.3% gold, and an 18K recycled gold ring still contains 75% gold, so the recycled source changes the sourcing story rather than the basic performance of a solitaire, pave, bezel, or cathedral setting.

Is moissanite a good sustainable diamond alternative?

Moissanite is a strong sustainable diamond alternative for shoppers who want sparkle, durability, and a lower price than many diamond options. It rates about 9.25 on the Mohs scale, so it can handle many daily-wear settings, but its rainbow fire looks different from the white brilliance of a GIA, IGI, or GCAL-graded diamond.

Do conflict-free diamonds and ethical diamonds mean the same thing?

No, they are related but not identical because conflict-free diamonds usually refer to stones not linked to armed conflict, often through standards such as the Kimberley Process. Ethical diamonds should address more issues, including labor, traceability, environmental impact, cutting practices, and disclosure through documentation such as grading reports, origin details, and a clear sourcing policy.

Can lab-grown diamonds go in an ultrasonic cleaner?

Yes, lab-grown diamonds are generally ultrasonic cleaner safe when the stone is secure and the setting is in good condition. Do not use ultrasonic cleaning on rings with loose prongs, delicate pave, emerald side stones, fracture-filled gems, or visible damage, and have a jeweler inspect a daily-wear 14K gold or 950 platinum ring every 6-12 months.
