All Herkimer quartz crystals in this group have an elongated shape. They are sharply double terminated and have excellent clarity. Definitely jewelry grade. Sizes are:
- 7x4.5x3.5 mm / .65 ct.
- 9x5.25x4.25 mm / 1 ct.
- 10.75x6x4.75 mm / 2 ct.
All three Herkimer quartz crystals have a bit of black hydrocarbon (anthraxolite) which gives them a rich hue. The 10.75 mm Herk contains a seed crystal. |
