About Ramben NYC
Three generations. One obsession. No compromises.
Third-generation gem traders with roots spanning India, Mumbai, and Siberia. The family legacy began with gemstone trading among the Maharajas of India, building a foundation of expertise, trust, and craftsmanship.
That tradition continued through generations, including specialized work in Yakutia, Siberia, where rough diamond cutting techniques were taught within government-operated facilities under some of the world’s harshest conditions.
Diamond District Legacy
Established on 47th Street since the 1970s, the business was built through generations of international diamond and gemstone expertise. With family roots in India, Milan, and New York, the legacy grew through global diamond trading relationships spanning Ramat Gan, Israel — one of the world’s leading diamond centers.
What began as a collaboration between family members in the gemstone and diamond trade evolved into a true family business, grounded in tradition, trust, and decades of industry experience.

With a longstanding presence in New York’s Diamond District, including operations at 15 West, the company has been specializing in diamond cutting since the 1990s.
