Lab grown or natural diamonds?
Both laboratory grown and natural diamonds are diamonds. Their main difference is how they form: in a laboratory or in nature. Here is what to consider when choosing your piece.
The same material, different origins
Laboratory grown diamonds have essentially the same chemical composition, crystal structure, optical and physical properties as natural diamonds. Natural diamonds form through geological processes. Laboratory grown diamonds are produced using technology, usually HPHT or CVD.
Can you see the difference?
Origin cannot be reliably determined by eye alone. Gemmological laboratories use specialised equipment to distinguish laboratory grown diamonds from natural ones. Cut, colour and clarity affect the appearance of an individual stone.
A lab grown diamond is not moissanite
Moissanite and cubic zirconia can resemble diamond, but they are different materials. A laboratory grown diamond is diamond. Always ask for a clear description of the stone in a piece.
Price and your choice
Laboratory grown diamonds are often offered at a lower price than natural diamonds. Compare stones of equivalent weight and quality, not carat alone. Choose according to the piece, your budget and what origin means to you. See current jewellery prices below.
What does a certificate tell you?
A grading report describes the stone examined and its origin. Read the details for the individual piece: a report for a centre stone does not automatically mean every small diamond has its own report. Cravingfor lists available certificate information on each product page.
