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.
A very unusual, old specimen with a slender stalactitic form and mysterious provenance. The Schortmann's minerals label that comes with this specimen dates it to the early years of their world famous dealership, about 1940. At that time a $5.00 specimen was a very costly piece. This period was the beginning of their historic association with Ed Over and Arthur Montgomery. The locale listed is the Cuvella mine in Nevada, which is not a "known" location. Whats more, the form of this piece is not like any I have seen from any locale worldwide, much less Nevada. It is 360 degrees crystallized with a central hole, micros of Barite and zoned dark inclusions, it looks almost violet in some lighting. In excellent condition with no eye visible damage, an interesting and mysterious piece. The stock number is typical of pieces that they obtained from older institutional collections both in the US and in Europe, but the meaning of the code is lost. Whatever the locale this is a fine and interesting specimen!
A very good, older specimen with the distinctive form that makes the Guerrero Amethyst world famous. From the "golden years" in the 1930's vintage mining, This is a single crystal with a few side crystals attached presenting the "fat belly" form with good (slightly better than average) color. The phantoms are also quite distinct and are more impressive in person reaching a deep grape purple color at the core. Some typical minor bruises are seen in the photos, and some side crystals have chipping, but these can be hidden by rotating the piece. I would rate this specimen as well above average for color, size and form but not a "super-top" piece (which in this size can be a 20-30K specimen!). A good value for a fine addition for any Mexican collection or quartz suite
