HOLD Zircon -classic locale
stock #HOLD 17.1-813
Store Kufjord, Seiland Island, Alta
Finnmark, Norway
5.4 x 3.7 x 3.4 CM (small cabinet/ large miniature)
price: $350


A complete, perfect and lustrous Zircon crystal sits well exposed on the classic matrix of Store Kufjord. The crystal does not have the cracks, pitting or other flaws seen on most of these. This old locale is one of the most famous for Zircon, every few years a few more pieces are excavated but never very many. This is vividly fluorescent in long wave UV and quite esthetic with a contrast to the white and black matrix.
Rhodochrosite- scalenohedral form crystals
stock #10.1-193
Uchucchacua Mine, Oyon Province
Lima Department, Peru
6.3 x 4.2 x 3.4 CM (cabinet)
price: $360


Sharp and gemmy red Rhodochrosite crystals on a contrasting matrix. The crystals are mostly formed as Scalenohedral but take a few other forms as well. Uchucchacua is one of the worlds best Rhodo localities for Scalenohedrons, but not as well known (or expensive) as South Africa. Several crystals are partly coated with a thin crust of what seems to be Calcite and makes a nice contrast.
Galena, Cerussite and Wulfenite -Classic
stock #16.1-704
Bleiberg District, Gailtaier Alpen and Karnische Alpen
Carinthia, Austria
7.5 x 6.8 x 6.3 CM (cabinet)
price: $480


From the type locality area for Wulfenite, this is a very choice, classic Lead secondary specimen. About a dozen distinct octahedrons of Galena are sparkling with hundreds of Cerussite crystals scattered on the faces. The spaces between the Galenas are full of orange to red Wulfenites in a blocky form. One of the great classic mineral localities, important since the early 14th century. In 1556 Agricola described the locality and methods in his famed "De re Metallica" . The mines closed for good in 1993, but left a great legacy of minerals and helped develop many methods in use today. This specimen is in remarkable condition, is far more attractive in person and a fine display quality Galena much better than most seen in collections from here.
Thompsonite -Ca
stock #18-AX-6-019
Aurangabad
Maharashtra, India
6.2 x 4.8 x 3.6 CM (cabinet)
price: $360


Sparkling pink balls of Thompsonite on a contrasting matrix- a very attractive specimen of this usually drab mineral. The outer surfaces of the balls are covered with tiny needle crystals that make the luster far more bright than most typical Thompsonite. This is from a small find about 6 years ago that was unlike any Thompsonite found before or since, and were perhaps the best specimens ever. We sold this piece some time ago it is now back and we are happy to have it. One edge of this piece has balls that show the inner structure along the side. The overall quality, color and condition is excellent and this is a super example of this more uncommon Zeolite. A colorful and attractive addition to any suite of Zeolites or Indian minerals.
Fluorite -deep purple -fluorescent red
stock #19.1-758
Mina Ojuela, Mapimi
Durango, Mexico
4.7 x 3.6 x 3.1 CM (miniature)
price: $330


Rich "royal purple" cubes on a contrasting gossan matrix from the prolific Mina Ojuela. Excellent transparenc with lightly etched faces this has the best color that can be found at this locality and has the rare brilliant red fluorescence that makes this Fluorite unique. In great condition as seen, the display side is undamaged there are some contacts on the backside only and not seen. Choice and eyecatching, the red UV response is especially strong on this specimen.
Elbaite -multi color zoned
stock #17.1-412
Santa Rosa
Minas Gerais, Brazil
3 x 1.5 x 1.4 CM (small miniature/ large thumbnail (toenail))
price: $420


A glassy, clean and many colored crystal of Elbaite from an old find (1970 vintage) at Santa Rosa. I count four or five colors at least with some gentle gradations. The termination is the flat basal type and has a hint of blue in some lighting but not so strong as a classic blue cap. In excellent condition though there are some tiny rough spots that are sub millimeter in size and not easy to see . A very nice gem crystal with a choice color pallet zoning from this get locale.
faden Quartz with tabular form
stock #AX-25-040
Waziristan Ophiolite, North Waziristan
FATA Federally Administered Tribal Areas, Pakistan
7.3 x 3.8 x 1.4 CM (cabinet)
price: $360


A perfect stack of tabular Quartz, gem clear and undamaged with a very distinct faden (string). The faden is at a slight angle off the C axis and is also slightly tapered. The flattened Quartz alone would be a very nice specimen, sharp, clear and lustrous but the strong faden and the textbook form make this especially choice. There have been occasional finds of faden quartz in Waziristan, this example comes from one of the last large pockets in 2015. Prior to these finds such a perfect Quartz from other locales would have been a magazine cover (and costly). The Waziristan Quartz finds did produce a lot of quite good pieces and the market price is currently much more affordable. Well above average and better in person too.
Spinel on Quartz and Calcite
stock #18.1-995
Pein Pyit, Mogok, Sagaing District
Mandalay Division, Myanmar (Burma)
2.8 x 2.3 x 1.3 CM (small miniature/ large thumbnail (toenail))
price: $350


Well exposed, complete octahedron of ruby Spinel perched on a sliver of matrix. A few tiny flecks pf Pyrite are present as well, but mostly this is about the deep red Spinel crystal. This has some of the typical pitting, rounded edges and adhering matrix but is otherwise a very pretty dark red gem crystal, There are a few small gemmy Spinel seen with magnification on the flat sides of the matrix, they are almost invisible by naked eye. Myanmar has a well deserved reputation for exceptional gem crystals, especially for Rubies. However for hundreds of years Spinel were often substituted for Ruby. The gem fields in Mogok produce far more Spinel than Ruby, and it has been increasing in acceptance as a legitimate and valued gem. This is a nice affordable crystal that is above average in quality.
