About BaystoneAbout Baystone
San Jose's premier destination for luxury natural stone, porcelain, and designer surfaces — where every slab tells a story of origin, craft, and timeless beauty.
A Legacy Built on Extraordinary Stone.A Legacy Built on Extraordinary Stone.
Founded over two decades ago, Baystone began with a singular vision: to bring the world's most exceptional natural stone directly to architects, designers, and homeowners who refuse to compromise on quality. Today, our 12,000 square-foot showroom houses an unrivaled collection of marble, granite, quartzite, porcelain, and designer surfaces. We maintain exclusive partnerships with brands like Versace Ceramics, Armani/Roca, and Walker Zanger — names that define the pinnacle of material luxury. Every slab in our gallery has been hand-selected from the finest quarries across Italy, Brazil, Turkey, and India — vetted for veining, color integrity, and structural excellence before earning a place on our showroom floor.
