Three C Grade Crystals  
Length: 19-22.75 mm
Width: 12.75-13 mm
Weight: 50.5 ct. / 10 g total

A trio of C grade Herkimer Diamond crystals with sharp and chisel tips. Sizes and descriptions:

  • Pictured center, a 19x12.75x10.5 mm / 18.7 ct. All but double terminated, both points are chisel tips. A well defined, 6 sided key mark is present. The center has cloudy inclusions.
  • The 20x13.5x11 mm / 16 ct. crystal is complete and double terminated, one sharp and one chisel tip. Tips have some matrix blemish. Clarity is great and a healed fracture and gaseous inclusion hold specks of black hydrocarbon.
  • This double terminated Herkimer Diamond, 22.75x13.9.75 mm / 15.6 ct., has two sharp points. One side is cloudy, the other clear. A seed crystal is seen just below one of the facets.

A termination point occurs when six faces (or facets) join together to form a point. When this occurs on both ends, the crystal is double terminated. While a single terminated quartz crystal is quite common, double terminated quartz is not. Herkimer Diamonds are one of the few quartz crystals on the planet that formed this way. A chisel tip is a termination defined by a flat edge rather than a 'point'.
