A GEM crystal of the HIGHEST quality with a faint smoky hue, makes this a superb specimen of classic Swiss quartz. The crystal measures approx. 9 x 3 x 2.5 cm in size and stands vertical upon a piece of granite matrix. The quality is literally ridiculous...you could not imagine better for a simple, plain, old quartz crystal from Switzerland. The luster is like glass, the clarity like a cut diamond. The crystal is pristine except only for one very small, tiny, shallow ding near the base of matrix. And, as most known, matrix crystals from here are hard to come by - let alone matrix pieces with such dramatic display! The crystal at the bottom is doubly-terminated, and 6 cm tip to tip, and pristine as well! Overall, its just a killer. Additionally, it comes with an old Harvard label denoting that it was collected in 1869 by a strahler named Caveng, or perhaps from the Caveng collection. It was deaccessed from Harvard to Phil Scalisi, hence to Hauck. I know it seems plain, on first site, but this is STUNNING and superb in person.
