Natural Herkimer quartz


Cluster of Herkimer Crystals

Atypical B Grade Crystal

Length: 23.5 mm
Width: 17.5 mm
Depth: 15.5 mm
Weight: 28.8 ct. / 5.7 g

At one time a much larger cluster specimen, these large and small Herkimer Diamonds have stayed together. 
The smaller crystal, which grew first, measures 11.5x9x7 mm / 3 ct.  It's double terminated, water clear, and cleanly separates from the larger. 
The larger measures 23.5x17.5x12 mm / 5+ g.  Shallow key marks are present showing where other crystals had grown.  Clarity is excellent.  One tip is sharp and clean, the other has just a touch of black where it grew against hydrocarbon.
We think it's fun to keep the specimen as two Herkimer Diamonds that fit together like a puzzle; but it could be reconstructed.  We leave it to you to decide.
