C-038 Cassiterite on Albite $190
Cruzeiro
Mine, Santa Maria do Suaçui
Minas Gerais, Southeast Region, Brazil
11.6 x 6 x 5 cm.
This neat mineral specimen features very large, very lustrous Albite crystals with many well formed Cassiterite crystals nestled amongst the Albite crystals and also features a little bit of Muscovite. In my opinion this is a excellent specimen, considering it's size, the association of minerals and great price. This specimen will get you a lot of “bang for your buck” as the saying goes.

A-031 Fluorapatite, Muscovite & Quartz $550
Darre Pech, Nangarhar Province, Afghanistan
12.5 x 9 x 4 cm.
I have seen many purple Fluorapatite crystals from many different localities, but I have never seen a purple one that formed in a prism like this pair have done. All of the other purple Fluorapatite crystals that I have seen have been tabular or short and fat. Another great feature of this specimen is that it is surrounded by many elongated crystals of Muscovite that are translucent. A great specimen for any pegmatite mineral collector.

L-013 Lepidolite $70 SOLD
Governador Valadares, Doce Valley, Minas Gerais, Brazil
6.1 x 3.9 x 3.5 cm.
This Lepidolite specimen features a myriad of shell-like layers that exhibit a metallic like sheen. This mound of “ball” Lepidolite is from a find made in the early 1970's. These “ball” Lepidolites are seldom seen for sale these days and are considered to be somewhat rare.

7.5 x 3.2 x 1.5 cm.
This mineral specimen features many pseudomorphs of Hematite after Siderite on a thin crystal of Smoky Quartz. A great mineral association specimen.

F-053 Microcline variety Amazonite $35
Madan Shar, Kabul Province, Afghanistan
3 x 3 x 2.2 cm.
This semi-translucent Amazonite crystal is from the one time find in late 2002. These were found when excavating a trench for a water or sewer (I can't remember which) line. Very few of these were preserved intact. A must have for any pegmatite or feldspar collector.

Q-096 Goethite on Smoky Quartz $45
Lake George, Park County, CO
4 x 2 x 1.3 cm.
This is a very dramatic mineral specimen in my opinion. A gemmy Smoky Quartz crystal with a spray of Goethite crowning it. These photos don't do this specimen justice. It is by far better looking in person.

T-104 Topaz SOLD
Virgem da Lapa, Minas Gerais, Brazil
20
x 10.6 x 6.5 cm.
2 kilograms (4.4 Lbs.)
I posted this specimen for those of you who like BIG crystals. This brute weighs in at a hefty 4.4 pounds. This crystal is complete, being contacted on the bottom with only a tiny ding on the bottom of the crystal. While not “gemmy” this crystal has good clarity along the upper portion and also exhibits a good color overall. While there are several internal fractures in the upper portion of the crystal they do not take much away from the overall beauty of this chunky specimen.

S-047 Scapolite on Feldspar $440 SOLD
Darre Pech, Afghanistan
6.8 x 3.8 x 2.5 cm.
Having seen an enormous amount of Afghani mineral specimens in the last 17 years I am amazed by the fact that almost every time my Afghani friend comes back from his homeland he manages to have at least one new find. This time it's this amazing Scapolite specimen you see before you. I sold most of them at Tucson and only 2 of them made it home. Of which, this is the only one remaining. Which surprises me since this specimen is different than all of the others which were small and chunky and unlike this one had no other minerals associated with them. While we're on the subject of associated minerals, in addition to the Feldspar, there is a crystal embedded in the upper left portion of the specimen that I have not been able to identify. Which in my opinion makes this specimen even more special.

Q-081 Quartz with Tourmaline (Olenite) inclusions $280 Reserved
Jenipapo Mine, Minas Gerais, Brazil
15.1 x 7.9 x 8 cm.
This specimen features a myriad of Olenite crystals, a rare form of Tourmaline (analysis done by Gunnär Farber) included in a very lustrous, terminated Quartz crystal. I found this specimen in the summer of 2005 in a mineral dealer's horde of old-time material from the 1970's. Although this specimen is contacted on the rear and on the bottom, I still think that for its price, it is an exceptional value, considering that most Tourmaline-included Quartz specimens have green or black Tourmaline as opposed to blue Tourmaline and the fact that the Tourmaline is Olenite which is many times rarer than Indicolite, the more common blue Tourmaline.
