Are a boutique lapidary studio located in Ithaca, NY. I highly recommend this company for precision faceting and beautiful rough gemstone sales. If you would like one of my designs cut they are a great choice to bring designs to life with exact angles and a perfect polish. Hashnu will ship gemstone rough internationally, and provides Ultra Tec equipment and faceting lessons.
