Tanzanite (blue Zoisite) gem crystal
Merelani, Umba Valley, Lelatama Mountains, Arusha Region
3 x 1.1 x .6 CM (small miniature/ large thumbnail (toenail))
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.
