From recent finds of Dravite in Tanzania, this is a very sharp, lustrous and surprisingly gemmy single crystal. Deep red brown color in excellent condition this glows with a backlight, in normal lighting it looks darker, more like the photos shown here.
SOLD Wulfenite on Mimetite
stock #SOLD Alec-18-030
Cerro Prieto, (San Francisco Mine), Curcurpe, Municipio de Curcurpe
6.5 x 6. x 3.5 CM (cabinet)
A very cute yet affordable Mimetite matrix with several sharp, undamaged Wulfenite windowpanes. Typical delicate gossan matrix with up to 1 CM crystal blades. Top San Francisco pieces are incredible and can be very expensive, this one is a more modest example but still pretty, in fine shape and not pricy.
stock #Alec 6-037
3.3 x 2.6 CM (miniature)
Thompsonite is usually a drab, plain white mineral but this find was something very special. In 2011 a small find of sparkling pink balls on a contrasting dark greenish matrix was made. There were very few pieces that were not damaged, and none found since. This is a pristine smaller piece with a single ball covered with sparkling micro needles. In good light it has a sort of cauliflower or brain-like look. A nice example that is a pretty addition to a zeolite or Indian mineral suite.

Monteponi Mine, Iglesias, Carbonia
4.4 x 2.8 CM (miniature)
A real prize winning miniature! (First Prize miniature catagory at MTL Mineral EXPO). It is impressive, esthetic gemmy and has classic form, from the most classic locality, Monteponi. An older specimen from this long closed mine, it is composed of 3 main intersecting crystals. Close exam finds very minor chipping mostly just on the base and backside, it can be displayed "eye clean". For this delicate mineral it is "virtually perfect". From an older collection, this quality is simply not for sale today. An older collection number is on the reverse side, it can be removed if that side is to be displayed. Choice!
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.
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.
Scheelite on Quartz
Tong Wha Mine, Neungam-ri, Angseong-myeon, Chunglu
5 x 2.7 x 2.3 CM (miniature)
A well presented, sharp, shiny Scheelite is perfectly perched on the side of a quartz crystal. Good Korean Scheelites were never very common 30 years ago and now are seen when older collections are dispursed. The Scheelite (1.7 CM) is translucent and has a few areas of selected etching. Overall in good shape, one tiny area of chipping can be found with magnification. A nice, esthetic and affordable old Korean piece.
Konar (Kunar) Province,
6.8 x 3.5 CM (cabinet)
A very clean pink to green Kunzite (spodumene) with great form and good pastel colors. Ex John Marshall Collection (with labels). From finds in the early 80's in Kunar this age ensures that the colors you see are stable and will not fade. Bi colored Spods are rare and they are clearly not irradiated or faked either. In good condition and mostly gem clear inside, a good gem crystal that will not break the bank.
