A highly unusual amethyst specimen - this being a slice cut from a single large crystal out of India. We do not know the exact locale, but I have seen large amethysts that might cut such sections out of Karur District, Tamil Nadu, India. It is 35 grams, and polished both sides. The inner patterns here are fascinating and unusual! From the collection of Hubert De Monmonier (1919-2007), donated by bequest to the University of Arizona Museum to add to their displays; and to provide specimens for the recent sale to establish an endowment fund for museum operations in perpetuity.
