Bournonite on Quartz

79 x 32 x 24 mm overall
with a 15 x 8 mm Bournonite

A fine, lustrous, doubly-terminated, clear to translucent Quartz crystal, measuring 79 x 32 x 23 mm, hosts a lustrous, tabular, sharply-terminated, dark-grey Bournonite crystal to 15 x 8 mm. The bottom of the Bournonite is contacted, and there is a small chip on the reverse side of the Quartz. It is much nicer and more 3-dimensional than the photos show. This is a great combo specimen from Yaogangxian.
