What the index will track
Validated records grouped by date, source class, shape, carat, color, clarity, cut, certification, asking price, and price per carat.
The IDAN Lab-Grown Diamond Price Index.
Price information should be useful, traceable, and honest about its limits. IDAN is preparing a recurring buyer-first view of lab-grown diamond pricing without publishing invented averages or stale market claims.
How it will be useful
Not as a substitute for assessing an actual stone. As a transparent context layer for understanding why two listings that look similar may be priced differently.
What it will not do
It will not promise a universal “fair price,” publish supplier-confidential information, or suggest a historical average is a quote for a currently available diamond.
