A fine cluster of thirteen Amethyst crystals on a Quartz matrix. The Amethysts have very good luster, and grade from a light purple in the lower halves to a beautiful deep purple in the upper halves, the likes of which is normally seen in the amazing Uruguayan Amethysts. The largest of these Amethysts is a 3.5 cm doubly-terminated crystal lying parallel to the matrix. Ex. Charlie Key Collection.
