Welcome to the House of Massin

A 19th century grand joaillier re-envisioned with 100% climate-neutral, fully traceable, lab-grown diamonds.

Masterfully designed in Paris, France, set and finished in New York City’s most revered private family ateliers.

Driven by the visionary techniques and ideas of our original founder, we carry Massin’s vision forward to set a new precedent for fine jewelry, pave the way for the next generation of creators, and do better by the world.
