We stock a wide variety of rocks, minerals, fossils, and semi-precious gems from around the world. These pieces range in form: polished spheres, standing freeforms, hearts, palm stones, tumbled, points and obelisks, slices and slabs, sculptures, wall hangings, etc. And of course we have natural crystals, rough, and raw stones in a range of sizes. Pricing depends on weight, quality, and relative rarity of the stone. We have dozens of stone varieties under $10, as well as larger or more rare and expensive specimens.
