A perfect, razor-sharp amethyst scepter with a pretty purple "blush" inside. 3.0 x 1.4 x 1.4 cm
Bright little uvites on gemmy quartz crystals, beautiful! 4.6 x 3.1 x 1.7 cm
A very pretty, translucent crystal of orange quartz from Madagascar. 3.4 x 1.8 x 1.8 cm
This old-timer comes with a label from W.F. Ferrier of Canada, dated to the last part of the 19th. century. Frieslebenite, a rare sulfo-salt of silver, lead, and antimony, can be found on this matrix specimen associated with drusy quartz, in euhedral crystals as large as .5 cm across. It is a gray-black color with evident luster. This is a large, rich, and very rare example of the species from its most famous historic locale! 9.7 x 5.5 x 3 cm
From a onetime find in Peru in the early 90s, this is said to be one of the very best specimens (the other being a famous thumbnail in the Ralph Clark Collection). This specimen, from the Peruvian subcollection of Cal and Kerith Graeber, is an attractive miniature overall and features two SHARP, LEMON-YELLOW crystals of 4.5 to 6 mm on edge. The helvites are sharply tetrahedral in form, and they are so sharp and colorful they look fake. It is a supremely good rarity, and a classic form Peru that is almost unobtainable. 5 x 4 x 3 cm
This is a visually striking specimen that starts out with a rim of emerald green, dioptase, to .7 cm across; on which are draped sparkling, snow white, spherical clusters of crystallized quartz, to 2.0 cm across. Perched aesthetically on the quartz are two rosettes of deep green, lustrous, PRIMARY MALACHITE crystals! This is very rare, especially on matrix, and even more so on matrix of dioptase! The malachite crystals are thin, elongated "rectangles" arranged in radiating 4-cm-wide clusters like a fanspray. i have never seen a specimen like this, and with the white quartz in between the two green minerals, no less! The side is rimmed with minor bits of plancheite, a copper silicate. The color contrasts on this specimen are just superb. The 3-dimensionality is impressive. Overall, its big, unique, and incredibly beautiful. I have NEVER seen a piece like this. IF YOU ARE TEMPTED, IT IS MUCH, MUCH BETTER IN PERSON! 11.3 x 10 x 5 cm
The discovery of wulfenite altering to quartz from the Finch Mine, in the last ten years, has made these specimens classics, because this type of pseudomorphing in nature is very rare. Reddish-orange crystals of quartz after wulfenite, to .6 cm across, cover the matrix. In addition, there are a few white rosettes of barite on some of the pseudo crystals. A most unusual occurrence! This is a rare cabinet-sized specimen from those finds, of about a decade ago. 9.2 x 4.9 x 3 cm
This is a UNIQUE matrix tourmaline! An etched, lustrous, translucent to transparent, royal blue, elbaite, to 4.5 cm in length, is perched on a 9.5 cm-long, gray, quartz crystal that has alternating frosted and gemmy faces. Most of the Otjua elbaites were varying colors of rubellite, so this royal blue elbaite is much rarer. In fact, I have NEVER seen another. This and the single following both came in trade from the private stash of Charlie Key, who obtained them some 20 years ago in Africa. The indicolite is really blue, not blue-gray as some have been, and stands out dramatically - more so, in person. 9.6 x 8 x 5.4 cm
Most of the elbaites from this mine were pink rubellites with a few blue indicolites. But this translucent, lustrous, elbaite crystal has rubellite which zones into a gemmy teal blue and then to an opaque, indigo blue at the termination. Some minor edge wear is present, but not distracting. This and the piece above both came in trade from the private stash of Charlie Key, who obtained them some 20 years ago in Africa. The indicolite is really blue, not blue-gray as some have been, and stands out dramatically - more so, in person. 3.2 x 2 x 1.9 cm
With the mine now closed, good to great rhodos are getting scarcer and more expensive. This particular specimen features crystals to 1.2 cm across which are lustrous, translucent, and a deep, rich, pink color. As is common with soft minerals, there are minor abrasions to a few crystals. This does not diminish the overall appearance of the specimen. I sell so few of them now for several reasons, the chief among them being that few of the quality i woul dhave settled for in the old days are available now, and i will not lower my standards to sell what IS generally avbailable....now, good ones come only in old collections receycling or from old dealer stashes that are getting smaller and smaller. 6 x 4 x 2.2 cm
Unusual! A slender, 4 cm long rhomb of translucent, rich pink, rhodo is aesthetically nestled between colorless, translucent, quartz crystals, to 4.0 cm in length. TThe rhodo is squished into a flat disc, but is a rhomb nonetheless. he huge size of China and its unlimited mineral potential, especially with a collector favorite like rhodochrosite, is going to dominate the new mineral market for years. 6.6 x 4.5 x 3.8 cm
A matrix of lustrous, colorless, quartz crystals, to .6 cm in length, is the host for a superb, lustrous, translucent, amber yellow, doubly terminated, sphalerite crystal, which measures 3.0 cm across. The aesthetics of the specimen are wonderful. This deposit is much better known for its world class copper and silver specimens. These very rare gem crystals came out in the 1980s. FEW gemmy sphalerites, twinned no less, are of this size! I have not seen a good one for sale in a long time. 7.2 x 6.6 x 3.4 cm
Translucent, lustrous, pseudo-octahedral crystals of orange scheelite, to 1.0 cm across, are nestled among colorless, transparent, quartz crystals, the longest of which measures almost 3 cm. This is from a new find in Pakistan, which I got ahold of recently! I have not seen others for sale, at least as of this time. NOTE: THIS IS NOT the same locality as previously known for Pakistani scheelite. 8.1 x 5 x 3.3 cm
This is a new Asian deposit for scheelite. At this early stage of development it is difficult to know whether the scheelite crystals will ever grow as large and as fine as those from China. On this specimen a single, lustrous, orange scheelite crystal measuring 1.2 cm across, is perched on top of glassy, colorless quartz crystals, to 1.5 cm in length. 7.9 x 6.2 x 4.5 cm
A cluster of orange,lustrous, translucent scheelite crystals, to 1.3 cm across, sit on matrix among colorless, lustrous, gemmy crystals of quartz, to 1.5 cm in length. 9.3 x 4.0 x 2.9 cm All Content and Design ©1996-2012 The ArkenstonePowered by http://mineralwebsites.comMineral Specimens by species; or by specimen id. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||
