A beautiful water clear Herkimer quartz crystal with an elongated shape and sharp natural double terminated tips.
A well defined key mark is present, as seen in the photographs. It strikes rainbows which is an unusual and favorable attribute in an AA grade Herkimer.
What makes this Herkimer quartz really unique is the black hydrocarbon rods, or spinel like inclusions. Hydrocarbon started as a thick oily substance that is now hardened and is quite common in Herkimer Diamonds. However, I have only seen it a couple of times as these thin spinel like inclusions. Hydrocarbon in the gems gives them a deeper rich hue.
Additionally, this crystal has at least 6 seed crystals scattered around the hydrocarbon. All are double terminated and well defined. A seed crystal is a teeny double terminated crystal completely encased in the larger gem. The smaller, of course, formed first, and it is very likely that these tiny baby crystals acted as seed hosts for growing the larger Herkimer Diamonds later.
This unusual Herkimer quartz crystal would be a great addition to any quartz collection.
