Grown Diamond Corporation USA

New York has 262 diamond dealer listings on SiteCity, and they cluster hard around a few ZIP codes. One ZIP alone holds 16 listings, with two more nearby ZIPs each holding 9. If you're near that cluster, you can likely visit several dealers in one trip instead of crossing the city. Elsewhere in New York, listings sit more thinly spread, so it's worth checking a dealer's ZIP before you plan a route.

Most listings, 252 of them, include a working phone number, so call two or three before you go and confirm hours or an appointment. Fewer have a website on file, 148 in total, so don't assume every dealer has an online presence to check first. Sponsored slots on SiteCity always carry that label when active, and none are running in this category right now, meaning the list you're scanning reflects raw directory data with no paid ordering. Own one of these businesses and see a wrong phone number or ZIP? Claim the listing and fix the details yourself.
