About Lab Grown Diamonds
Lab grown diamonds are real diamonds — chemically, optically, and physically identical to mined diamonds, and graded by the same independent laboratories (IGI, GIA). The only meaningful difference is that they are grown in weeks rather than formed over billions of years.
Choosing lab grown means a larger, cleaner, more colorless stone for your budget, with a transparent origin and no mining footprint. This diamond is IGI certified — you can verify its grades directly on the IGI portal.

Frequently Asked Questions
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are 100% real diamonds — same crystal structure, same hardness (10 on the Mohs scale), same optical brilliance as mined diamonds. This centre stone is a colorless, VVS2 clarity diamond, IGI certified.
What is the beaded frame?
A milgrain-beaded gold surround traces the oval, adding a soft, antique-inspired detail around an otherwise clean solitaire. It frames the stone and gives the ring vintage character without any side stones.
What metals can I choose?
10K, 14K or 18K solid gold in yellow, white or rose, or platinum. The ring shown is 14K yellow gold.
