Three C Grade Herkimer Diamonds  
Length: 14.75-19 mm
Width: 11-11.5 mm
Weight: 28+ ct. / 5.6 g total

A trio of raw Herkimer quartz crystals with very good clarity and hue. Clarity shows much better in person than the pictures depict. Sizes and descriptions:

  • A 14.75x11x10 mm / 7.5 ct. with a single sharp point and excellent clarity.
  • A quality 15.5x11.5x9 mm / 9.5 ct. is all but double terminated with excellent clarity and a deep hue.
  • The 19x11.5x9 mm / 11.3 ct. has a twin tip that's super clear. The other termination is cloudy, but sparkly.

All have some matrix occurrences and black hydrocarbon present. A hydrocarbon is a thick oily substance. This oily substance moved through the cracks and vugs of dolomite, along with dissolved quartz, salt and other minerals. When it solidified, it left the solidified hydrocarbon. Previously this black material was referred to as anthraxolite; it is only recently the new theory of hydrocarbons has been introduced.
The hydrocarbon give these quality Herkimer quartz crystals their deep hue.
