About Us


A legacy four generations in the making, the Duneier story began with Max Duneier, an Austrian emigrant who arrived in New York City in 1910 with a single suitcase and a lifelong passion for exquisite gemstones. 

Years later, his son Clyde took over the business. Under his expertise, the firm became synonymous with the highest quality stones and precious metals—deepening the reputation for integrity and excellence associated with the Duneier name.

 Today, the third and fourth generations of Duneiers run the business, building upon tradition and upholding the values forged over the last century.
