Tanzanite (blue Zoisite) gem crystal
stock #19.1-869
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
3 x 1.1 x .6 CM (small miniature/ large thumbnail (toenail))
price: $750


An especially vibrant, sharp and clean gem crystal in impeccable condition. The intense blue hue on this is far better than the average and the crystal shows well the famed color shift to a strong royal purple as it is rotated. As the gem values for good Tanzanite is so high the cost of a good specimen with top color can be prohibitive. This is an exception, a small miniature with big visual impact for well under 4 figures. Many Tanzanites have been heat treated to enhance color, it is almost impossible to tell. This one has a hint of red color when viewed down the C axis from the termination. That is said to be a good indication that the color is fully natural.
Tanzanite Multi Color zoned crystal
stock #14.1-042
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Arusha Region, Tanzania
3.1 x 2.2 x.9 (small miniature/ large thumbnail (toenail))
price: $925


A sharp gemmy Tanzanite crystal with a strong color change and dramatic zoning. Top grade glassy luster and a lot prettier in person, this shows color changes from yellow to green in the top part, and blue, purple and red in the lower part that is hard to appreciate in photos. The overall condition is fine, there are some small contact rough spots on the backside that are not easy to see and are completely invisible from the display side. The front of the specimen is clean, sharp and undamaged. Far better in person and a great value for such a clean example!
Tanzanite (gem blue Zoisite)
stock #7AE-353
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Manyara Region, Tanzania
2.2 x 1.4 x 1.1 CM (thumbnail)
price: $350
Spring 2019

A Tanzanite crystal with excellent color change. This is well terminated, glassy deep blue to purple crystal in good condition. The tip of the termination is especially transparent and shows a nice blue "cloud" inside. The backside of the crystal shows a more complex area that has stepped faces and is likely a recrystallized contact. A nice specimen of the specie that is reasonably priced
Tanzanite (very fine, zoned blue-green Zoisite)
stock #A 148-104
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
Arusha Region, Tanzania
5.3 x 1.5 x 1 CM (small cabinet/ large miniature)
price: $2250


An very impressive, sizable and sharp crystal with great luster and strong color change wit the added feature of a well defined internal color zone stripe that is very rare. Displays great with good clarity, only one very tiny edge chip is noted that is almost invisible to the naked eye, and not visible from the best display side. The most impressive feature is the distinct color changes as this is rotated, The color is an intense blue, then a zoned green, rich purple and from along the c axis a strong red. With good backlight a small yellow zone is also seen. With the costs of even average gem Tanzanite being incredibly high, this is an ecxeptional piece at a great price.
