At Hashnu Stones & Gems, we work and play with some of nature's finest creations, gem stones, opals, agates, jaspers, and fossils. We custom facet and carve a great variety of materials for our patrons, collectors, jewelers, artists and our friends. We also provide fellow lapidarists with facet-grade quality rough material for their own creations.
