AA Grade Herkimer Crystal

Length: 12 mm
Width: 11 mm 
Depth: 8.5 mm
Weight: 5.71 ct. 

This Herkimer Diamond comes in it's own display case.  It's shown in the photo below, wish it would have photographed better.
It has a interesting shape and a large well defined key mark. A key mark is recognized by a geometric pattern that is usually three or six-sided. It's the impression where it grew against another crystal, but didn't attach. The keyed crystal grew at a later date, around the original crystal, the step-like pattern indicating the growth pattern.  Photos above clearly show the key.  We're including a 10x loupe to fully appreciate it.
Internally clean and water clear, it's an unusual Herkimer Diamond specimen.

Price: US$ 110.00
