Different from Helvine crystals from other Chinese provenances, these are isolated, sharp and formed by the positive and negative rhombohedron, with the color between dark honey brown and yellow distributed in zones. They are on a matrix coated with orange trapezohedral Spessartine crystals and leafy aggregates of Chlorite. The Helvine has been analyzed and we will send a copy of the analysis to the buyer.
