An incredibly rare, rich example of scheelite from this classic locality best kown for cassiterite , as long ago as 250 years. I have seen small, ugly, insignificant scheelite specimens in the past but none of this magnitude, and with such good documentation and pedigree in any case. It is much prettier in person, by the way. Note the old labels....he acquired this personally from Sir Russell who in turn acquired it from the collection of H.F. Collins (as noted on the Russell label included) 9 x 6 x 4.1 cm
In the last few years, there has been a plethora of new material from China. However, this is without question one of the nicest combo pieces I have seen of ANY mineral. They came out, mostly through Dan Weinrich, in the late 1990s and really set the market on fire with the vibrant color and lustre of these sharply crystallized sphalerites. The beautiful contrasting matrix is a crust of micro quartz crystals over thin rock shards, giving a uniform sparkle and lustre to the background: vibrant red and white colors contrast where the quartz lifts off from the matrix a bit to be clear or takes on the red of the hematite-stained matrix underneath. Crystals of gray galena, some spinel twinned and aesthetically perched on quartz are, in turn, bracketed by two, lustrous, red, gemmy, sphalerite crystals of about the maximal size for the find. The largest displayed sphalerite crystal measures 3 cm across. The largest galena crystal is almost 1 cm in length. To top off this remarkable specimen, two, frosted, creamy white, calcite crystals poke their terminated faces straight at the viewer , midway between the dominant sphalerite crystals. These calcite crystals reach 2.5 cm long. The piece is completely covered with sphalerite around to the underside (lower-left), as well. This specimen has a huge WOW factor! 14.2 x 9.1 x 6.2 cm
Aesthetically nestled in a bed of colorless, transparent quartz crystals, to 3.0 cm in length, are several parallelhubnerite crystals: dark red, with bright red, gemmy, highlights. I have never seen such thick AND gemmy hubnerites and the contrast with the stark white quartz is incredible. This is a VERY choice piece that came out in the 1980s and has long been in a private German collection. The lustre, color, sharpness of the crystals is superb. It is nice that they have REAL terminations instead of the usual fuzzy-terminated style from the locality where the terminations just sort of taper off. Here, we have lustrous, chisel-shaped faces. The largest hubnerite crystal measures over 5.0 cm in length. The color and crystal contrast, again, is just MUCH BETTER IN PERSON to the point i guarantee you won't even believe its the same piece when you hold it in good lighting, compared even to these nice pics. For my taste, its the best Peruvian hubnerite, if not the most expensive, that I have ever had the opportunity to offer. 6.1 x 4.9 x 4.5 cm
This is an unusual specimen in that it is a complete floater: a crust of translucent, pastel pink, inetergrown fluorite octahedrons to .5 cm across, COMPLETELY covers one face of a flattened, gemmy, light smoky, quartz crystal. The quartz crystal measures 8 cm across and again, is complete all around. The fluorite is preferentially only on one side, while the back of the specimen is the flat major face of the quartz crystal. VERY RICH AND COLORFUL with lots of pink for the price! 8 x 6.7 x 2.4 cm
This combo piece features several cubes of fluorite, to 2.8 cm across , which have been coated by drusy, lustrous pyrite crystals. All this is aesthetically perched on a lustrous, radiating knoll of quartz crystals, reaching 1.0 cm across. COMPLETE ALL AROUND and brighter in person! An unusual yet interesting Moroccan piece! 5.1 x 4.5 x 4.3 cm
On a matrix of sparkling white, drusy quartz, which has a very nice sculptural quality, is a crust of rich pink, lustrous, intergrown, platy crystals, of rhodochrosite, which have formed flower-like, rosettes. The largest rosette measures .7 cm across. The crystal quality is extremely high for the locality! Note that the paler hue of pink in the second photo, the closeup, is more accurate. 9 x 6.7 x 1.8 cm
11.3 x 8.3 x 7.3 cm
A CLASSIC: razor-sharp crystals of anatase on gemmy quartz crystals, from Norway. The focus is on the perfect 0.7-cm crystal right on the side face of the large, gemmy quartz crystal. Not many of these pop up on the market anymore, even out of collections (since they long since stopped being mined). I don''t recall seeing a single one for sale at the last Tucson show with any dealer, including all the hotel and Main Show dealers, though of course they do occasionally turn up here and there. ex Ruggiero collection 6.8 x 5.6 x 3.1cm
Brassy, striated crystals of chalcopyrite accented by scalenohedrons of milky calcite. Mined in Zacatecas in the 70''s. ex Ruggiero collection 7.7 x 6.9 x 3.9cm
A big, sharp and beautifully-formed 3-cm apatite crystal set off by a cluster of quartz crystals - from the classic green apatite locality. Note also the microcrystalline apatite which has deposited itself between the quartz crystals! 5.1 x 4.7 x 4.1cm
Some of these smokies coming out of the locality where the amazonites are being found are just STELLAR - I mean, look at this crystal! It''s hard to see how it could be much better - gemmy transparency, super sharpness, and just the right natural "base" of matrix. 11.6 x 5.3 x 4.8cm
A sharp, dramatic "bulls-eye" agate, highly sought-after by collectors (particularly in these days of stratospherically-climbing prices for fine agates, launched perhaps by Dave Wilber''s "legitimization" of collecting them). ex Swoboda collection 5.7 x 5.0 x 1.9cm
This is a superb old Sweetwater galena out of the Leithauser Collection, with sharp, lustrous spinel-twinned crystals to 2 cm. The galenas are selectively coated on one side of the specimen with sparkly microcrystals of quartz and chalcopyrite; choose your favorite display face! 7.6 x 5.9 x 5.2cm
Look how these crystals of galena are isolated amongst the gemmy quartz crystals! In particular, there is one fine triangular crystal that has wrapped itself around a quartz crystal in back, so that it looks as though the quartz crystal is shooting through the galena. A beautiful combo specimen from Bulgaria. 8.7 x 6.2 x 5.9cm
In one place, the calcite has created a stacked "Christmas tree" appearance on the quartz! On the back, a cluster of quartz crystals is selectively coated with a secondary growth of calcite absent from the front side 5.8 x 4.9 x 4.9cm All Content and Design ©1996-2012 The ArkenstonePowered by http://mineralwebsites.comMineral Specimens by species; or by specimen id. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
