Tri-State Mining District
Collected Late 1950's — Former Belden Collection
Size: 3 3/4" X 3 1/2"
Description: I just love this piece!
The main crystal is clean, sharp and measures 1 1/2" long.
What's so awesome about the specimen is that the scalenohedral crystal displays highly detailed internal cleavage structure - this feature being what led
Renť Just HaŁy to experiment with the geometrical law of crystallization. Will a need stand for upright display.
