Cornerstone Minerals

Cornerstone Minerals sells fine mineral specimens, crystals, rare fossils, natural history pieces, and jewelry. The collection includes cabinet and large specimens, thumbnail minerals, carved crystals, tumbled stones, and décor items, with stones and specimens sourced from locations around the world. Shoppers can also find sterling silver pendants, necklaces, and earrings set with gemstones.

The business opened in 2005 in Asheville, North Carolina, after more than a decade of attending mineral conferences and trade shows. It is now located in Charleston and sells through an online store that also offers gift cards. Many listings are one-of-a-kind pieces, so availability changes as items sell.
