Ron Moyá - Master Diamantaire and Jeweler

"The world may be full of stones, but true quality is still rare. That’s what I bring.”

Ron Moyá is an Israeli-Portuguese jeweler with over 30 years of experience. As a GIA-certified expert, he became one of the most famous sought jewelers in New York, known for his skill, honesty, and eye for rare stones.

He worked with some of the world’s most valuable diamonds, including the 110.03-carat Sun-Drop Diamond, which sold for $10.9 million at Sotheby’s Geneva, and the 12.03-carat Blue Moon Diamond, which sold for $48.4 million in 2015. These sales helped build his name in the global jewelry world.

Luxury brands like Bulgari, Tiffany & Co., Harry Winston, and De Grisogono have sourced stones through his network. His strong connections and deep knowledge helped bring rare gems into some of the most iconic high jewelry pieces.

Ron entered the Asian market after seeing a clear problem: the demand was strong, but quality was often lacking. He made a promise to raise the standard—bringing world-class stones, trusted sourcing, and true craftsmanship to clients across Asia.

To deliver on that promise, Ron handpicked a team of certified jewelers and experienced production staff. Each one brings deep knowledge and skill to their craft. Together, they produce every piece with precision and beauty.
