About Oscar Massin
Oscar Massin: The Future State of Diamonds
On a mission to set a new precedent for fine jewelry, forging a brighter path toward a sustainable world. Inspired and evolved from the legacy French house of Oscar Massin. Born in 1829, Massin was a master craftsman and innovative designer, deeply committed to the integrity and elevation of his craft. He studied the structure and engineering of diamond settings in the service of naturalism—resulting in extraordinary pieces that celebrate light and organic growth.
Our Collections
The new Oscar Massin collections take their inspiration from Massin’s most revered techniques, including his use of intricate filigree work to create the illusion of thread, as well as, his illusory settings, designed to celebrate the diamond by minimizing the setting around it.
Our Commitment to Sustainability
All Oscar Massin collections are designed in fully recycled 18k white and yellow gold using 100% climate-neutral Latitude® diamonds; the stones are “as grown,” meaning they have no post-growth enhancements, resulting in the highest, type IIa purity level—present in only 1-2% of diamonds across the globe—both physically and chemically identical to their mined counterparts.
Latitude® diamonds are the first to be SCS-certified for sustainability, achieve 100% climate neutrality and a net zero carbon footprint, accounting for both current and legacy emissions; they also have 99.9% accurate US origin traceability through the entire U.S. chain of custody, and are governed by the core principles of ethical stewardship.
