Sphalerite, quartz, calcite – Shuikoushan Mine, Changning Co., Hengyang, Hunan, China

Particularly aesthetic hand specimen with calcite and sphalerite on a matrix covered with quartz. Two levels rise up like wings, covered with small crystalline quartz and "garnished" with calcite and sphalerite.
The sphalerites have an intense color and an excellent shine.
A gem for any mineral collection from China.
