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.
Herderite (hydroxl Herderite) on Microcline
stock #Alec-14-368
Shigar, Skardu District, Baltistan
Gilgit-Baltistan, Pakistan
5.5 x 4x 3.5 CM (cabinet)
price: $900


From the late 1990s vintage finds, a very distinctive, doubly terminated gem crystal perched on a crystal section of Microcline. The 3 CM long Herderite is in perfect condition and shows textbook form. Excellent esthetics and a slight color change from blueish to greenish in different light sources. A far better than average piece, and there has been nothing new on the market for several years.
