Description: A beautiful clear, gemmy quartz crystal (60 x 17 x 15 mm) with very light smoky colouring in its upper half and slight milkiness in its lower half, sits to the side of a matrix of (mostly) quartz, shared with several other smaller, clear quartz crystals.
The main crystal, which has a female termination, has a few interesting patterns on some of its termination facets, and a few gas and other inclusions. One of the lesser crystals has an interesting pressure mark to the side.
The main crystal seems almost perfect, but on looking closer, one can see a very narrow nick running across nearly half of the female termination point, and along an adjoining ridge. Most of the lesser crystals have little or no damage, but a few of them (sitting on the matrix) have broken off, and there is some damage to the edges of the matrix.
The specimen displays well on a flat surface, with the main crystal sitting at an angle of rougly 55º.
