Questions About Adamas Necklaces

Are Adamas diamonds real?
1 Answer
1stDibs ExpertOctober 7, 2024
Yes, Adamas diamonds are real. However, the luxury jewelry maker specializes in lab-created diamonds. Although its gemstones are real in terms of their chemical composition, they are human-made rather than sourced from mines.
