White diamonds vs CVD: a colour grade is not a growth method
People often say “real diamond” when they mean a white diamond: colourless or near-colourless on D–Z. CVD is not a colour. It is a way of growing a crystal in a chamber, usually in weeks. Mixing white diamonds and CVD on one catalog trains the eye to shop sparkle only and to forget what the letter D was for.
White diamonds here
D–Z colour on a certified stone in this catalog. Cut, clarity, and carat still matter. Origin and the report sit with the stone when you buy.
CVD
A diamond grown in a laboratory, usually in weeks. We do not list CVD, HPHT, or other laboratory-grown goods next to the white, fancy, or black collections.
What we mean by white
In this house, white is the D–Z collection. The letter describes how little colour shows in the face-up view. It does not describe a factory process. Cut, clarity, and carat still matter. Colour is still a letter from D to Z.
What CVD is
CVD — chemical vapour deposition — grows diamond from gas. HPHT is another laboratory method. Both can produce a crystal that is optically diamond. Neither has the history a mined stone carries, and neither belongs in our three collections.
Why we will not list both
- A buyer of white diamonds is paying for a D–Z look and for origin they can stand behind. A CVD aisle next to it makes that story optional.
- CVD is priced as a manufactured product. White diamonds in the trade are priced as graded crystals with a different market.
- Fancy and black have the same rule: no laboratory-grown substitute in the same drawer.
If you want a white diamond, stay on this site in the white collection. If you want hue, use fancy. If you want a black diamond, use black. We do not sell CVD. Certificate details for a listed stone are shared when we quote.
