Quartz v. Herkimer
Middleville, Herkimer County
8.3 x 6 x 7.1 CM (cabinet)
Worldwide mix summer
A blocky matrix with druzy Quartz hosting several very clear, undamaged Herkimer type Quartz. The diamonds are mostly colorless but a few are the golden type, and all are very clear and lustrous. The largest crystal has a very big internal bubble cavity that holds unusual worm like petroleum inclusions. These are vividly fluorescent and have three distinct colors. A fine and impressive cabinet piece that is especially interesting under the microscope.
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!
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.
