Mina Ojuela, Mapimi
5.7 x 4.6 x 1.9 CM (cabinet)
Adamite crystals standing up from the limonite matrix in both white and light mint green colors. Early seventies vintage specimen from Mina Ojuela, ex Les Hitchings collection. Vivid fluorescence and in excellent condition. A few Calcite crystals are also on the matrix but this is mostly all Adamite. So much good Adamite came out during that period in many habits that these were under respected. Currently much less is coming out and we know this was a golden age for the worlds best examples of this specie. Choice display with good visual impact for the size.
Heights Mine, Durham, Weardale County
4.1 x 3.3 x 3.3 CM (miniature)
Perfect and well composed Fluorite from the Heights mine. This cute miniature has a prominent, well isolated and very sharp cube perched on top. The edges and corners are sharp and perfect on this, the luster is glasslike and the Fluorites are quite transparent. No visible damage. A good value for a small, choice classic British Fluorite with a quality well beyond typical.
Quartz on Chrysocolla and Malachite
Phelps Dodge Morenci Mine, Morenci, Copper Mt. Mining District, Greenlee
11.6 x 8.1 x 6.2 CM (cabinet)
A large colorful Copper secondary display specimen from an old find in Arizona. A druze of tiny clear Quartz crystals is covering many green Malachite balls and areas of bright blue Chrysocolla. The overall effect is sparkling and vivid in person. A sizable specimen from Morenci. The bulk of the matrix is layers of Chrysocolla in several shades of blue looking like a rich Turquoise. Some of those thin layers seem to be "gem Silica" that when thick enough is highly sought after for Lapidary. These layers are too thin for that and the surrounding Chrysocolla is quite brittle besides. The matrix has been properly stabilized to keep it from cracking as some Chrysocolla can do. This piece is early sixties vintage and simply eyecatching.
Fluorite with phantom zoning
Okorusu Mine, Otjiwarango District
5.7 x 4.3 x 3.7 CM (small cabinet/large miniature)
Gemmy Fluorite cubes of blue-green color in a cluster on minimal matrix from Okorusu. This Fluorite has well defined inner phantoms of a darker violet-blue color and some cubes have a thin color zone extra near the outer edge. This specimen displays well from either side. The main crystals are prominent, sharp and clean, the only damage seen is minor on the outer edges where this was removed. Most Okorusu Fluorites are damaged, or the crystals are very tightly packed together, this is a nice exception. The mine has been inactive now for about three years and may be gone forever.
Choix, Municipio de Choix
6.2 x 3.9 x 3.7 CM (cabinet)
"Wet-look" luster on bubble-gum pink Smithsonite from Choix. In undamaged condition, this is from the early finds made by Benny Fenn. This locality in Sinaloa is not currently producing, it has however in the past yielded many great colors and forms of Smithsonite. This is a good clean small cabinet size that shows the color and habit well. A thick layer with nice luster shows the inner structure on the edges.
stock #SOLD 8.1-397
11.6 x 4.8 x 2.8 CM (cabinet)
Simply put this is a really ugly mineral that can even have an unpleasant odor. A natural parrafin waxlike substance derived from Hydrocarbons, this looks much like a rotted banana, it is translucent and has a density less than 1 so it floats. This is an old specimen from Poland with a 1930-40 vintage Schortmann label, this piece is now almost completely odor free perhaps because of its age. However the literature tells us that heating to a moderate warm temperature or any rubbing will again produce the bad smell along with a negative electric charge. The name comes from the Greek meaning "stench wax". This is a super strange mineral that is never seen for sale (and I have never been asked for any either). This locality is not listed in Mindat but that may be due to the many changes to the names and geography of that area over the past hundred years. Certainly not a specimen for a collector of fine esthetics, but a large example of a legitimate mineral almost never seen in any collection. Weird.
Chuquicamata Mine, Calama, El Loa Province
6.3 x 4.4 x 4 CM (cabinet)
A superb very well crystalized example of this rare Copper Sulphate from Chuquicamata. Good Antlerite in prismatic crystals from this long ago find is not often available. These crystals are in the 3-4mm range which is about as large as any known from this legendary locality. Under magnification a variety of forms are noted and most of the individual crystals are well isolated, gemmy and brightly colored. This locale was at one time the source of many incredible rare copper minerals including rare copper Halides and what were for a century the worlds best Antlerites. A small newer find at Milpillas has since produced larger crystals with a different habit (and a far higher price). Chuqui was developed into one of the worlds largest open pits with efficient mechanized processes that now of course destroy any specimens at great speed. I have visited the site several times in the past decade but never found even a crumb worth obtaining, nothing is coming out. This piece is obviously from long ago.
Gem clear terminated Beryl crystal that has several inner channels or tubes. There is one small tube that opens in the middle of the termination but the others are closed inside the prism. In excellent condition a nice pale green crystal with a termination that has both a tapering form and a flat top. It is incredible how many variations and modifications of Beryl that have been found over the years, and Brazil in particular has been the source of many unique habits.
