A Grade Natural Quartz Crystal

Length: 20 mm
Width: 15 mm
Depth: 11.5 mm
Weight: 18.89 ct.

A fantastic double terminated Herkimer Diamond crystal. The terminations are special, as one is the traditional sharp point, while the other is a chisel tip. A common termination point occurs when six faces (or facets) join together to form a point. An alternate is when the facets come together with a flat edge. This is not as common, and referred to as a chisel tip. This double termination gives the crystal a unique shape.
Some tiny keys and growth area are present on a facet near the chisel termination. A 2 mm baby bridge is also present and can be seen in the pictures. All other facets are smooth and clean.
Internally clean but for a single bit of black hydrocarbon (some refer to as anthraxolite). It reflects as multiple specks in some of the pictures. With a loupe you can see it's encased in crystal.
Also, a ghost-like inclusion flashes an occasional rainbow.
It's a generous size for such a water clear and double terminated Herkimer Diamond. Truly a borderline AA grade crystal.
