This singluar Aquamarine crystal has excellent hexagonal prismatic form with a flat basal face truncated by a few tiny, sloping secondary faces. It appears to have no huma-induced damage and clean faces and edges. An indentation where a partially-intergrown crystal was removed is visible near its base, where it intersects two prism faces and two edges. It has a very pale blue color, a vitreous luster, and is transparent and mostly very clear. There are several tiny, radiating clusters of what I believe to be tourmaline in the lower half of the crystal. These crystals are colored black and are thinner than human hairs; they do not exceed 2 mm in length. The upper half of the crystal is quite clear until about 2 mm below the termination. At that point there is a very cloudy layer that extends almost to the top of the crystal, where there is another tiny thin band of clarity. Looking down on the termination face, one can see that this cloudy layer does not extend to the full radius of the crystal, so that there is a thin border of clarity around its edges, and it has a definite hexagonal shape. The crystal is affixed in a domed plastic thimble box.
