New Lab-grown Diamond Report
The GIA is now including information about a diamond's production method in its new lab-grown diamond reports, which it calls LGDRs. The new reports will specify whether the diamond was created by either the chemical vapor deposition (CVD) or the high pressure high temperature (HPHT) method and whether there are indications of post-growth treatments to change the color. Take note.
