About Us
A&D Gem Corp. is one of the leading importers of colored stones in the United States, and has been servicing fine retail jewelers as well as dealers for almost half a century.
Established by the Kordvani Brothers, Abe, David, and Johnny, in 1969, A&D Gem quickly emerged as New York’s premier source for fine precious stones.
Famously known in the industry as the “Kings of Emeralds”, A&D has created their niche in the industry. With the irreplaceable knowledge of Emeralds, Rubies, Sapphires, Tanzanites, and Alexandrites, it is no wonder why A&D has risen as the leaders in fine precious gemstones.
A&D Gem’s finished jewelry division, Jewels By A&D, was created over 15 years ago.
With their exceptional expertise in precious gem stones, in combination with their team of master craftsmen and designers, Jewels By A&D has created countless “One of a Kind” pieces set in 18 Karat Gold and Platinum. Integrity, quality, price and service have become the heart of A&D, and is the reason why they have become one of the fastest growing jewelry companies in the United States, and has now established itself as a leading manufacturer in the industry.
