Amethyst, Mamuju Area, Sulawesi Barat Prov, Sulawesi island, Indonesia
Size- 9.0cm x 7.0cm x 4.0cm
Sparkling purple balls of Amethyst or "grape stone" as it is known. Recent study on this material has shown it to be amethyst crystals, just in a really unusual form. Specimans are getting hard to get due to the mines being mined out. A very nice specimen.
