About Semi-Precious StoneAbout Semi-Precious StoneAbout Semi-Precious Stone

Semi-precious stone surfaces transform actual gemstones — amethyst, agate, tiger eye, labradorite, and sodalite — into full-size slabs for countertops, feature walls, and furniture. These materials represent the absolute pinnacle of natural stone luxury, with each slab composed of thousands of individual crystals or mineral formations set in resin or cement to create a functional surface of astonishing beauty. When backlit, semi-precious stone slabs become luminous art installations. Bay Stone Depot curates one of the Bay Area's most extensive collections of semi-precious slabs, each one personally inspected for quality, translucency, and visual impact.

Amethyst$150–$400/sqft
Agate$100–$300/sqft
Tiger Eye$200–$500/sqft
