Everything you need to know to make an informed decision about your diamond purchase
Understanding Diamonds
Choosing a diamond is one of the most important purchases you'll make. Our comprehensive guide will help you understand the factors that determine a diamond's quality, beauty, and value, empowering you to make the perfect choice.
The 4Cs of Diamonds
The universal standard for assessing diamond quality
Cut
The Most Important Factor
Cut determines how well a diamond reflects light, creating its brilliance and sparkle. A well-cut diamond will appear more brilliant than a poorly cut diamond of the same carat weight.
Color
From Colorless to Light Yellow
Diamond color is graded from D (colorless) to Z (light yellow). The less color, the higher the grade. Colorless diamonds (D-F) are the most valuable.
Clarity
Internal and External Characteristics
Clarity refers to the absence of inclusions and blemishes. Most inclusions are microscopic and don't affect the diamond's beauty to the naked eye.
Carat
Weight, Not Size
Carat measures a diamond's weight, not its size. Two diamonds of equal carat weight can appear different in size depending on their cut and shape.
Diamond Shapes
Each shape has its own unique character and appeal
Round
Classic and brilliant, the most popular choice
Princess
Modern square cut with exceptional sparkle
Cushion
Vintage-inspired with rounded corners
Oval
Elongated brilliance, appears larger
Emerald
Elegant step-cut with hall-of-mirrors effect
Pear
Unique teardrop shape, very distinctive
Marquise
Elongated with pointed ends, maximizes carat
Asscher
Square step-cut, Art Deco elegance
Lab-Grown Diamonds
Understand the origin and characteristics of your stone
What Are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds created in controlled laboratory environments using advanced technology. They have the same physical, chemical, and optical properties as mined diamonds.
How Are They Made?
Two methods are used: HPHT (High Pressure High Temperature) mimics natural formation conditions, while CVD (Chemical Vapor Deposition) grows diamonds from carbon-rich gas.
Are They Real Diamonds?
Yes! Lab-grown diamonds are chemically identical to mined diamonds. They're not simulants like cubic zirconia or moissanite. Even experts need specialized equipment to tell them apart.
Why Choose Lab-Grown?
Compare individual lab-grown and mined diamonds by their characteristics and price. Ask for evidence behind origin, sourcing, and environmental claims rather than relying on a general label.
