Are Effy emeralds real?
1 Answer
1stDibs ExpertMarch 13, 2024
Yes, Effy emeralds are generally real. However, not all pieces feature natural emeralds. The luxury jewelry maker uses a mix of naturally derived and lab-created gemstones in its jewelry. Experts consider lab-created emeralds to be real gemstones, but they are inexpensive compared to natural stones. Because lab-grown diamonds don’t meet our luxury jewelry standards, 1stDibs does not allow listings that are inclusive of lab-grown diamonds on the platform (this policy is also shared by major auction houses). However, fashion jewelry that features lab-grown or cultured gemstones other than diamonds can be found on the site. On 1stDibs, explore a collection of Effy jewelry from some of the world's top sellers.
