A very attractive light lilac/ violet gem crystal of Scapolite from this important locality. This is actually 2 crystals grown together with the terminations staggered and showing great glasslike luster. No damage by naked eye but with 10X magnification there are some very tiny contacts and a very insignificant chip that need to be mentioned. A very nice example of a mineral that is usually quite nondescript!
stock #7 BRAZ 212
Irai, Alto Urugual region
Rio Grande do Sul, South Region,
12 x 9 CM (cabinet)
Two perfect radiating clusters (suns) joined together in an impressive and esthetic piece of glasslike quartz. No damage at all, a fine purple hue that grades to a clear outer edge the piece is fully transparent and glows with even a hint of backlight. Not the typical quality, this is a fine mineral specimen for a fine collection.
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
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.
