About Baystone

Who we arein stone.

Bay Stone Depot is a stone showroom in San Jose. Everything we sell is here in the yard, ready to see, touch and compare.

We stock luxury natural stone — marble, granite, quartzite and designer surfaces — alongside tile, mosaics and outdoor stone. Homeowners come here to choose the slab for their own kitchen. Contractors come here for materials they can count on and a team that knows the inventory.

We source from quarries around the world, and we have served the Bay Area from San Jose since 2007. Our advice is plain and our selection is large. Walk the yard and let the slabs speak.

What We Offer

Curators of the fineststone.

From the mountains of Carrara to the quarries of Brazil, we source materials that belong in serious architecture. Every slab is chosen for its veining, color and integrity.
