"The world may be full of stones,
but true quality is still rare.
That's what I bring."
A Record of Brilliance.
Having curated some of the world’s most valuable diamonds—including the $10.9M Sun-Drop and the $48.4M Blue Moon Diamond—Ron has served as a trusted partner for iconic luxury houses such as Bulgari, Harry Winston, Graff, and Tiffany & Co.
Through his global network, he has placed rare gems into some of the most iconic high jewelry pieces in existence.
A New Standard.
After years in the diamond and gemstone world, we saw a clear gap in Asia. The demand for fine jewelry and rare stones is strong, but many clients are still left without proper guidance, transparent sourcing, or a clear understanding of quality and long-term value.
Ron Moyá was created to change that. We bring the level of care, discretion, and technical expertise expected in the world’s leading jewelry markets to clients across Asia.
We work privately with each client to source exceptional natural or lab-grown stones, create custom fine jewelry, and guide them toward investment-grade rare stones.
