About Us
AgacciNYC was built by hand, on New York's Diamond District — 47th Street, where fine jewelry has been made for generations.
We didn't start as a website. We started at the bench: setting stones, custom-building gold and diamond pieces, and learning what makes a piece last a lifetime versus fall apart in a year.
Our Diamonds
Today, we bring that same craftsmanship to certified lab-grown diamonds — the same fire and brilliance as natural diamonds, chemically, physically, and visually identical to mined diamonds, at a price that makes sense. Every stone we offer is independently graded, so you always know exactly what you're buying.
Our Craftsmanship
We're a small, independent business — not a warehouse, not a dropshipper. Every piece is made with the same care we'd put into a custom order for someone walking into our office on 47th Street. From delicate everyday essentials to statement pieces, our jewelry is made to elevate your daily style and celebrate life's most meaningful moments.
Our Promise
- Independently certified diamonds
- Hand-set, made-to-order craftsmanship
- Real people, real accountability — not a faceless warehouse
- Fine jewelry made to last
When you buy from AgacciNYC, you're buying from people who've spent their careers in this trade and stand behind every piece we sell.
AgacciNYC — Brilliantly Made. Beautifully Responsible.
