15 x 12 x 6.4 cm. This very unique and interesting Spruce Ridge plate is dominated by a large (4.4 cm) scepter crystal that is amethystine at the top. It is zoned, not phantomed nor sceptred. The effect is most unusual and really beautiful in a subtle manner. The large crystal is framed by smaller quartz crystals, the larger of which also have amethystine terminations. The luster is good and the crystals have more clarity than could be shown in the picture (they are water clear). This is a unique, large, and very appealing quartz plate from a remote and hard-to-collect locale, visibly distinct from just about any other quartz specimens.
12.2 x 6.2 x 4.8 cm. Galena with minor sphalerite and quartz from the Krushov Dol Mine in Madan. The galena has the highly prized "melted look". Excellent example from this now classic locale.
12.5 x 9.4 x 6.0 cm. A nice specimen consisting of a feldspar rock matrix hosting a lot of undamaged and perfectly terminated jet black arfvedsonite crystals (up to 2 cm) with a great luster. Arfvedsonite is a fairly rare amphibole in nice macroscopic crystals. Also present are smoky quartz crystals and white orthoclase which provide a nice contrast to the black arfvedsonite.
6.2 x 5.9 x 6.1 cm. This specimen of well-crystallized Stannite from the Yaogangxian mine in Hunan, China features numerous groups of well-defined, brassy-colored Stannite crystals in association with several sharp and very clear Quartz crystals and a sprinkling of white Dolomite and Muscovite Mica. There is a lot of Stannite on this specimen; in fact, half of the matrix is composed of Stannite. It is not quite pristine (just a little damage at the periphery edges of the cluster) but is close to it. There is even a Stannite-lined vug on the right side of the piece. The Quartz crystals all have perfect tips, and some of them even contain Dolomite-covered phantoms in their terminations. Not only is this a very rare species, but to find it in such an aesthetic composition with three other well-crystallized minerals is wonderful. The stannite has excellent luster, and crystals to 8mm.
3.0 x 2.7 x 1.7 cm. Monazite gets its name from the Greek word "monazein", which means "to be alone", in allusion to its isolated crystals and their rarity when first found. Monazite is usually found in granitic pegmatites, but these crystals are found in hydrothermal tin veins where is an absolute absence of Thorium (usually a trace element in Monazite). This is a remarkable, very well crystallized, very rare, specimen hosting sharp, lustrous, translucent, orange-pink, twinned crystals of Monazite-(Ce) measuring 5 mm on Quartz crystals on matrix. These twins are some of the most distinct and impressive twinned Monazite crystals I have seen from Bolivia. The crystals actually show a color change in different lighting ranging from orange-pink to a yellowish color depending upon the light source. This specimen has some of the largest crystals I have seen from this mine, and it just came out of the ground a few months ago (20009). This piece is from the same mine in which this material was discovered along the Contacto and San Jose veins in this mine and was first described by Sam Gordon and Mark Bandy.
5.3 x 3.5 x 2.5 cm. Recently some very impressive and attractive specimens of Scorzalite were found at the Estaño Orcko mine in Bolivia. For some time these specimens were thought to be Lazulite, but Brian Kosnar was the one who first reported (through analysis) that they are indeed Scorzalite (the iron analogue of Lazulite). For the size, luster and overall quality of the crystals, they are certainly some of the best Scorzalites to reach the market in a very long time. This particular specimen hosts a few sharp, very lustrous, deep inky-blue, monoclinic crystals of Scorzalite measuring up to 3 mm with Quartz on matrix.
6.0 x 4.8 x 3.3 cm. A great small cabinet size specimen featuring wonderful quality, sharp, gemmy, lustrous, prismatic, purple color crystals of Amethyst measuring up to 2.5 cm sitting atop gemmy, lustrous, sharp scalenohedra of Calcite with underlain "Chlorite" on matrix. This piece is remarkable for Bolivia as it features a type of crystallization that is virtually unheard of from any mine down there.
5.9 x 4.6 x 4.2 cm. A nice Colorado old-time specimen accompanied by an old Hugh Ford label. The photos hardly do it justice as it is much more impressive in person and, when closely examined, one can see that there is a significant amount of veined gold on the surface. Ex. Evan Jones and Hugh Ford.
12.9 x 9.3 x 3.5 cm. A spectacular cabinet piece of babingtonite, backed by prehnite and quartz. All of the babingtonite crystals are pristine. There are two generations of babingtonite. The first generation consists of jet black, lusterous crystals to 1.8 cm. The second generation is micro crystals that can be found on the babingtonite, prehnite, and quartz. The backside has more prehnite and less babingtonite. From finds of 2008-2009.
13.5 x 7.2 x 5.3 cm. These are true classics from this famous mine which is most well known for its impressive Epidote and Quartz association specimens. This larger cabinet sized piece features dozens of deep green, blocky, prismatic Epidote crystals with good form and luster which are associated with very slightly smoky color, gem to gemmy, lustrous Quartz crystals. Ex. Richard Kosnar Collection.
9.1 x 4.1 x 2.1 cm. This is a very attractive association specimen from one of the most famous classic Peruvian localities. Several sharp, lustrous, prismatic, parallel growth crystals of Hubnerite form a crystallized "fan" with several gemmy Quartz crystals and rarely seen grey Native Arsenic on the reverse side of the piece. There are some minor spots on this specimen where the characteristic blood red color can be seen reflecting in the light. These crystals have not been seen with much frequency in years, and they are among the finest Hubnerites ever found. The piece comes from the famous Richard Kosnar collection and is amazingly good shape for the material.
6.4 x 6.1 x 5.6 cm. This beautiful combination piece is from the famous Hedgehog pocket found around 10 years ago now, named for obvious reasons for the spiky quartz protruding out, on which the gem rhodochrosites sit. The rhodochrosites, as typical from this pocket, are extremely sharp and rhombohedral with clear, gemmy faces. They are either translucent, or in some cases fully transparent so that you can look down through them to the quartz on which they are impaled. A few small crystals of pyrite and hubnerite are a bonus association here. This specimen is good on the front and back, with crystals on each side (though it is much richer on the front). The largest crystals reach just under 1 cm on edge, and about 1.3 cm across the long diagonal. Weighs 275 grams.
6.9 x 3.7 x 3 cm. The Messina mine is home to a unique and beautiful occurrence of these bright blue ajoite-in-quartz specimens. Seldom do you see a specimen so richly included, with such intensity, as this one. The core zone of color, approximately 2.5 x 2 cm of the front face, has an incredibly rich saturation of the minute ajoite inclusions (a mineral very rare from other localities and seldom concentrated). The crystal is complete-all-around and has moderate inclusions in its upper half, though the front display is most impressive. It has a fine termination, excepting only a rough indentation , a natural contact where it grew against something, at a plateau above the colored zone leading into the peak of the termination. Direct from recent mining here, this is a superb and colorful example.
10.7 x 7.3 x 7.2 cm. The fabulously rich silver mines at Guanajuato, Mexico have produced some outstanding amethyst specimens and this is an excellent and unusual combination example. This fine, two-sided cabinet piece is distinctively different, than most you see from any other locality. There are actually two generations of quartz on this piece, which is wonderfully peppered with milky-white calcite rhombs on one side. The frontal face is composed of interesting looking, doubly terminated amethyst crystals. The sharp amethyst terminations are composed of water-clear, colorless quartz. Looking down onto the crystals gives a surreal phantom-like look. Uncommonly very fine material from this famous locale. Old finds, circa 1970s or early 1980s. Ex. Consie Prince Collection.
20.7 x 5.3 x 2.9 cm. The photo does not show how very sparkly and dramatic this large cabinet drusy quartz stalactite is. This specimen is translucent and is a pleasing, pastel sea-foam-green. Complete-all-around and pristine, except for the broken sidecar stalactite at the base. Jalgaon has produced tonnage of zeolites and comparably few quartz specimens like this, which really stand out.
