A wholesale partner, not just a vendor. We source our own diamonds, control the manufacturing, and deliver the finished jewelry — with the playbook to sell it and the data behind the why. For America's most discerning retailers.
Every partnership starts with a deep study of your business. Your customer mix, your floor layout, your top SKUs, your gaps. Before we recommend a single piece, we need to know what's already working — and where the missed margin lives.
We come back with a custom sell-through strategy: new SKUs scoped to your customer, merchandising guidance for your floor, and the business context behind every recommendation. The playbook is the deliverable — the product is the proof.
Digital catalog. Real-time inventory. Drop shipping and order fulfillment on every SKU we stock. Quarterly reviews on what's moving and what's coming next. The first shipment isn't the end of the work — it's the start of the relationship.
Balancing design, value, craftsmanship, and retail performance.
Built on long-term thinking, transparency, and collaboration.
Every detail serves a purpose — from product to presentation.
Evolving quickly with retail, manufacturing, and technology.
Most wholesalers send the inventory and call it done. S&J Diamond controls the chain from the diamond to the finished piece — sourcing our own stones, directing manufacturing across the world, and routing every program to the supply chain that fits your customer. Then we build the strategy to sell it. The product is where we start, not where we stop.
Every partner gets a custom sell-through strategy — built around your customer mix, your location, your price tier, your floor. We've spent three decades learning what moves and why. You inherit all of it.
We source our own diamonds, natural and lab, and our colorstone — then direct a manufacturing network across the world. For each partner we route to the supply chain that fits: so the quality meets your customer, and the price holds on your floor.
We don't push a piece because it's in inventory. We push it because we've studied your business and we know who buys it, why it sells now, and what margin it commands. The why is the work.
S&J Diamond Corp has worked in New York's Diamond District since 1995. The team that built the company is largely the team that still runs it — so our partners deal with people who remember every program they've ever run with us.
We don't sell to consumers. We exist to make our retail partners faster, more profitable, and more certain in every piece they put under glass. The jewelry is where we start — the playbook and the data are the rest.
