MD-121051 - Stibiconite - - Archived San Luis Potosí, Mexico cabinet, 10.3 x 2.8 x 1.2 cm.
10.3 x 2.8 x 1.2 cm. This is a classic from Mexico: a large, sharp crystal of stibnite (antimony sulfide) that has been pseudomorphed by stibiconite (antimony oxide hydroxide), the sulfur atoms having been lost in the process. This is not a surface replacement or coating, but a true pseudomorphing, where the crystal is stibiconite clear through, but retaining the sharp form of the former stibnite.
MD-137554 - Stibiconite, Stibnite, Calcite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico large cabinet, 16.1 x 4.4 x 4.1 cm.
16.1 x 4.4 x 4.1 cm. While these pseudormorphs are not the most beautiful things in the world, they are great Mexican classics. That is, IF you can find one of this quality - which is extremely rare. The stibnite looks to have completely altered to stibiconite. The very large crystal is complete, undamaged and un-contacted, and terminated. But, most importantly, there is this beautiful cluster of calcites around the bottom that makes this really unique and aesthetic, since the vast majority of these are just single crystals with no matrix or attachments.
MD-176461 - Stibiconite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico cabinet, 12.3 x 3.0 x 2.8 cm.
12.3 x 3.0 x 2.8 cm. A cabinet-sized cluster of tan stibiconite pseudomorphing sharp stibnite crystals from Real de Catorce. The original striations of the stibnite are still distinct, as are the sharp terminations. Ex. George Elling Collection.
MD-181554 - Stibiconite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico large cabinet, 22.9 x 8.5 x 5.4 cm.
22.9 x 8.5 x 5.4 cm. A large example of this classic Mexican pseudomorph. The original stibnite has been replaced by stibiconite, retaining the sharp form of the stibnite crystals. Ex. University of Delaware Mineralogical Museum.
MD-19416 - Stibiconite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico small cabinet, 9 x 3.6 x 2.2 cm
Stibiconite has replaced a crystal of stibnite, sharply retaining its form. A fine Mexican pseudomorph (unuusally good compared to most of these critters). 9 x 3.6 x 2.2 cm
MD-203240 - Stibiconite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico large cabinet, 24.0 x 5.5 x 4.7 cm.
24.0 x 5.5 x 4.7 cm. A superb, huge, and pristine stibiconite pseudomorph after stibnite from the John Sinkankas Collection. This huge specimen is very aesthetic, with the branching crystal at the base. The pure secondary stibiconite forms white patches on the pseudo. These are not the most colorful of mineral specimens, but are classic, old-time pieces from Real de Catorce.
MD-223864 - Quartz, Stibnite, Stibiconite - - Archived Trinity Mts, Lovelock, Antelope District, Pershing Co., Nevada, USA thumbnail, 2.4 x 1.2 x 1.1 cm.
2.4 x 1.2 x 1.1 cm. A unique and unusual thumbnail quartz crystal from near Lovelock, Nevada. A sharp, glassy, transparent quartz crystal is filled with inclusions of white stibiconite needles and a few black stibnite needles. Ex. Dick Jones Collection.
MD-228392 - Antimony, Stibiconite - - Archived Arechuybo, Chihuahua, Mexico miniature, 3.7 x 3.1 x 2.7 cm.
3.7 x 3.1 x 2.7 cm. A rare, showy and heavy specimen of bright metallic native antimony from a very uncommon locale in Mexico - Arechuybo, Chihuahua. This is a vein formation with the brassy antimony lathes to 2.2 cm running completely through the lighter matrix of stibiconite. Older material. Ex. Mullane Collection.
MD-24369 - Stibiconite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico small cabinet, 7 x 1 x 0.8 cm
A sharp stibnite crystal that has been replaced by the mineral stibiconite, retaining the original form perfectly. These are not the most beautiful of mineral specimens, but they deserve respect as a classic from San Luis Potosi. 7 x 1 x 0.8 cm
MD-27145 - Stibiconite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico small cabinet, 8.4 x 2.1 x 1.0 cm
A SUPERB, classic and pristine tan stibiconite crystal cluster from Catorce, Mexico. Mexican stibiconites may get larger than this, but they DO NOT get any better. Old dealer stock of Dr. Gary Hansen and not shown since the early 1980s! 8.4 x 2.1 x 1.0 cm
MD-27213 - Stibiconite - - Archived Catorce (Real de Catorce), Mun. de Catorce, San Luis Potosí, Mexico small cabinet, 8.3 x 1.4 x 0.9 cm
While not the most beautiful specimens on earth, these pseudomorphs are a Mexican classic. The stibiconite has replaced the stibnite, retaining the form and the perfect sharp termination. 8.3 x 1.4 x 0.9 cm
MD-52112 - Stibiconite, Stibnite, Baryte - - Archived Xikuangshan Sb deposit, Lengshuijiang Co., Loudi Prefecture, Hunan Province, China large cabinet, 28 x 18 x 5.5 cm
On a thin plate of matrix quartz are piled up dozens of thick, flattened rhombs of barite. Stretched across them is a 21-cm(!) pseudomorphed crystal of stibiconite after stibnite! These are well-known from Mexico, but NOT from China, and certainly not in a specimen of this magnitude! An certainly not displayed so nicely on matrix as this! Other smaller crystals, including a pretty spray, are elsewhere amongst the barites. Stibiconite is not something i usually recommend to anybody, as its typically earthy, dull, and boring. But THIS specimen is a real showpiece. Its only drawback is the sheer size of the barite plate, and that it won't fit sizewise in many collections. In fact, I complained about that when buying it, and so got it more cheaply for the reason, and am passing it on for the same reason. If you have the space , though, this IS a really fascinating talking-piece. 28 x 18 x 5.5 cm All Content and Design ©1996-2010 The ArkenstonePowered by http://mineralwebsites.comBy-species Galleries | ||||||||||||||||||||||||
