It explains how GIA and IGI report lab-grown stones, including GIA's switch in October 2025 to describing lab-grown quality as Premium or Standard, and what to expect on price and resale, in general terms and with no prices. The sources, mostly GIA, are listed at the bottom of the page.
Shopping for a stone or a custom ring? Moda Diamonds sources both, and every diamond Moda sells is certified.
