Our Story
Four Decades of
Unmatched Excellence
Since 1984, Onyx Realty has redefined what it means to represent extraordinary property — quietly, precisely, without compromise.
Who We Are
Elevating the Standard of Luxury Real Estate.
Onyx Realty was founded on a single conviction: that the world's most extraordinary properties deserve representation that is equally extraordinary. We do not merely list homes — we curate legacies, connecting singular estates with those discerning enough to appreciate them.
Our philosophy is rooted in discretion, precision, and an unwavering commitment to the interests of those we serve. We operate where the market is thinnest and the stakes are highest, trusted by heads of state, global executives, and generational families alike.
Bespoke Curation
Every property we represent is personally vetted against our proprietary 47-point quality standard.

All client relationships and transactions are protected under ironclad confidentiality agreements.
