How Much is a Investment Grade Diamond?
- 1stDibs ExpertNovember 6, 2023The best cut grade for a diamond varies by rating system. The Gemological Institute of America (GIA) ranks the best cuts as Excellent, while the International Gemological Institute (IGI) has Ideal at the top of its rating chart. Keep in mind that only round brilliant-cut diamonds receive cut grades. There are no ratings for other cuts like the marquise or the emerald. And remember, if you're shopping for an antique diamond ring, instead of dedicating yourself to finding the perfect cut or stone, focus on the one that best expresses your personal style. Explore a diverse assortment of diamond jewelry on 1stDibs.
