About Diamondaire

The founders of Diamondaire are diamond dealers. In the diamond industry, diamond dealers operate inside the supply chain itself — sourcing stones directly from the rough, trading loose diamonds, and supplying inventory across the market.

That’s very different from most jewelry retailers. Traditional stores usually purchase finished stones from wholesalers and resell them to customers. Diamond dealers work closer to the source, dealing directly with the stones before they ever reach retail.

Because of this, Diamondaire has access to the full diamond market — natural diamonds, lab diamonds, rare gemstones, and custom cuts across global inventories. We’re not buying stones from the plug. We are the plug.

Diamondaire operates from a private office in the New York Diamond District, where we work directly with clients on custom jewelry from start to finish. Diamond sourcing, CAD design, manufacturing, and stone setting are all handled in house.

If you can imagine the piece, we can make it happen.
