The US Stone Group B2B Portal connects stone buyers and suppliers around the world, with one trusted name in the middle. Suppliers list their stock — blocks, slabs, tiles, stone handicrafts, mineral specimens, crystals and loose gemstones — with pictures, videos, sizes, quality details and prices, organized in the same stone categories as our collections and identified only by their US Stone Group partner number. Business and retail buyers alike browse the material, choose what they want and confirm their order with a secure online payment. US Stone Group officials then inspect the material at the source, run the quality check and send the buyer the full inspection report. Once the buyer approves it, we supervise the container loading and take care of the shipping. The minimum order for blocks, slabs and tiles is one full container, while handicrafts, specimens, crystals and gemstones are available in smaller quantities, and every material traded through the portal is inspected, documented and backed by US Stone Group. For buyers, it feels like buying local even when the stone crosses an ocean: your contract, your payment and your point of contact are all with US Stone Group, an American company in Westminster, California — and every overseas headache, from inspection to freight to customs, is ours, not yours.

B2B Stone Trading, Inspection & Container Loading
The US Stone Group B2B Portal brings stone suppliers and buyers together under one trusted name. Suppliers of marble, quartzite, granite, travertine, soapstone, semi-precious stone and porcelain can list blocks, slabs, tiles, stone handicrafts, mineral specimens, crystals and loose gemstones for inspection, and business and retail buyers source verified material — from full container loads to individual pieces — without ever dealing with an unknown supplier. Buyers work with an American company from start to finish — US contract, US dollars, US accountability — while we shoulder the overseas side: inspection, loading, freight and customs.
From our base in Westminster, California, our inspectors examine every listed material at the source, supervise packing and container loading, and follow each shipment until it arrives. Tell us about your stock or the material you are looking for, and our team will take care of the rest — inspection, quality-check reports, secure online payment and logistics.
