An AESTHETIC and VERY RARE combination piece of gemmy and glassy, tabular, light blue aquamarine crystals 2.7 cm highlighted by a cluster of lustrous, greenish-black kesterite crystals. The matrix is sparkly lepidolite. This is simply an outstanding specimen, with the aesthetic, free-standing aquas, but ESPECIALLY in the association with the kesterite. Kesterite is a rare copper, zinc, iron, tin sulfide and this is a super combo piece from Mt. Xuebaoding, China.
