A super fine thumbnail from the one time find (a single pocket) at the Benchmark quarry that produced these remarkable phantoms. The Quartz has the typical form of a Herkimer Diamond, but there is a small black stem that extends into the center of the transparent head. The stem is hexagonal and clearly seen inside the clear Quartz. Flawless condition and very sharp, this is even more clear and lustrous in person. A classic USA thumbnail, this like every other piece was collected by Bill Hladysz and had been in his collection.

Pre Holiday 2017

A Northeastern US mineral legend, the black stemmed scepters of Herkimer are quite rare and despite hundreds of diggers toiling in the hard Dolomite only a few are found every few years. From a recent exceptional pocket this is a perfect example with no damage (extra rare) and doubly terminated (crudely) which is almost unheard of. The black stem is partly deep smoky brown with a few tiny areas of transparency. The top is sharp and glassy and also has dark inclusions some of which are brightly fluorescent. A fine small example of this most uncommon of Herkimer Diamond Quartz!
Quartz (Herkimer diamond) with prismatic voids

Ace of Diamonds mine, Herkimer

8.5X5.2 CM (cabinet)
price: $250


A sizable, sharp and glassy pair of intergrown Herks that have far better than average clarity. These have some fine bubbles. anthraxolite flakes and tubes included within, but the best is the rare "crystal voids" that are cavities shaped exactly like a small doubly terminated quartz. Contacted on the rear and with a few chips but still displays well and the inclusions are easy to view.
