Stunning cluster of bi-colored Tanzanite crystals. The crystals are gem quality and complete with purple/blue body color and yellow terminations. Clusters are much less common than single crystals and this one presents superbly with two major diverging crystals. Additionally there are smaller crystals and some attached Graphite at the base that give a slight 'matrix' visual effect. Highly aesthetic and undamaged Tanzanite specimen. Weighs 17.83 grams.

Large single gem quality Tanzanite crystal. The crystal displays purple on the front face, blue from the side, and a light pink/red up the C-axis, confirming this is a natural and unheated crystal. The crystal is complete all around and undamaged. The termination has mostly flat crystal faces with one large face that has a shallow 'valley' from natural etching or irregular growth. The crystal is internally flawless (gemstone cutting quality) over much of it's length and has significant gem rough value. Weighs 123 carats with about 75 carats being clean facet rough quality which would yield about 26 carats of finished gemstones. Cut Tanzanite gemstones of this color retail for $500/carat, giving this crystal approximately $13,000 of gem value if it were cut. But I like it much more as a crystal.

Terminated single Emerald crystal from recent finds in Nigeria. Highly transparent and glassy with some horizontal color banding. Complete all around, undamaged, with a smooth, flat termination. This is a crystal that someone reserved last year when I first got the lot but never paid for, and now listed here for the first time. I will note that the camera doesn't pick up the green and brightness of these very well and they are better in person. Weighs 1.31 grams.
