A large and fine single Octahedron of mint green Fluorite with the very desirable "stipple faced" or melted look on the crystal faces. This Alpine Fluorite is sizable and impressive from a location that has not produced good material for many years. Pasto Bueno Fluorites are quite highly regarded, and and also rather distinctive. This one is in fine shape on the display side but it is cleaved where it was removed on the underside. Displays very well and a bargain for such a large crystal.
Pyrite (striated cubes)
stock #7- AC 180
Huanzala Mine, Huallanca district
Dos de Mayo Province, Huanuco Department,
11.8 x 9.2 CM (cabinet)
An fine, unusual and well balanced older piece from what has become a very famous mine for great pyrites. This form is not like the material that Huanzala has produced for the past decade, this has sharp slightly modified cubes showing pronounced striations. There are many great forms that Huanzala has produced and some fine suites have been developed to showcase them. This would be a fine addition to such a suite, or for any collection of good esthetic minerals. The cubes are sizable, the largest 6.5 CM. Minimal damage, the main crystals are very clean, there is some chipping and periferal damage on the rear and lower areas, despite that it is still very esthetic and presentable.
A HUGE and impressive monster that is doubly terminated, top gem grade yellow triphane. Sharp, glassy lustre and damage free with only some tiny bits of matrix adhearing to the main prism which is over a foot long!. One end has the classic hackly / fibrous termination while the other shows a staggered pair of prismatic tips with some fine growth hillocks. This crystal like all fine gem spodumene is highly dichroic and shows an excellent orange -pink transition on the C axis. The piece has been in a private collection for several years and the color (unlike many) is quite stable. Good triphane has never been plentiful. This one seems to have been from the major find of 99-2000 and I have not seen much new material available over the past few years, and none as large and fine as this. I consider this a very fine display piece that is both reasonably priced and will likely have outstanding investment value
Simply a very impressive pink flourite! Huge for the species, esthetic and with good color, this is a very fine pink fluorite from a find of 3 years ago that was very limited. The largest crystal here is an impressive 6.6 CM tall. There are some faces with selective frosting and small growth hillocks that are classic for the better alpine Fluorites. All of the fluorite XLls have some muscovite bits adhering and embedded in some faces and some contacting is evident too, This is a minor distraction since overall the form and color make this a very fine display piece of the most sought after Fluorite. If this was French or Swiss (or even Peruvian) the price would be exponentially higher. This one is certainly a fine investment and a very good value!
A pinkish matrix of crystalized Microcline is host to many yellow- green crystals of Fluorapatite many of which are doubly terminated. These crystals are a little greener than the classic Mexican Mercado examples and with a very different matrix. This is not a common locality. There are some broken crystals evident.
Franckeite (var Potosiite)
San Jose Mine, Oruro
7.5x4.6 CM (small cabinet/ large miniature)
Potosiite is the rare Tin poor variety of the rare mineral Franckeite, and was a separate species until it was discredited in 1997. It is still a very rare Sulfide with crystals larger than micros considered huge. From a small find of the worlds largest and best crystals at the San Jose mine, this is a top example with individual crystals to 1.3 cm. For this rare and ugly mineral this is a true killer and even esthetic! This was rated as one of the best 7 pieces found.
Urumqui, Kuruktag Mts.
Xinjiang, Uygur region,
9.8x7.6 CM (cabinet)
Brilliant red wulfenite from this new discovery, crystals reaching 1.7 CM densly cover the gossan matrix. There are 2 different unknown micro crystals coating some areas and the Wulfenites show a selective coating of what looks like quartz on some faces. There is some damage on some crystals which is true of all the larger pieces from the find, but the overall impact is still excellent. There is disagreement over the correct location details on this find, we will keep everyone informed as we try to sort this out and confirm the source.
A very nice miniature with a well formed tabular aqua sitting perfectly on matrix. A great value too, the Aqua is a sizable 4.5CM and has a nice pale blue color, with no damage at all. Hot glued on a plastic base for display this is easily removed if desired.
