SM516 - Pyrite $ 600 Huanzala Mine, Peru small cabinet - 9 x 6.5 x 5.5 cm ![]() ![]() ![]() ![]() Large 4.5cm Pyrite crystal atop smaller crystals. Specimen is composed solid, highly lustrous Pyrite. Bright and showy.
SM512 - Brucite $ 450 Killa Saifullah, Balochistan, Pakistan small cabinet - 6 x 4 x 3 cm ![]() ![]() ![]() ![]() pinwheel formation of translucent yellow Brucite on matrix from recent finds in Pakistan. Undamaged and good from both sides. Reminiscent of a Mapimi Adamite.
SM530 - Prehnite $ 280 Merelani Hills, Arusha, Tanzania miniature - 3.5 x 3 x 2.2 cm ![]() ![]() ![]() ![]() ![]() Cluster of translucent yellow Prehnite crystals. Such yellow Prehnites have come from Merelani sporadically over the years, but never before in the quality that has been found in the last year. This specimen has big chunky crystals that stick out in various directions. Some chipping, but nearly a floater crystalled all around, a good one for the find.
C631 - Stilbite on Quartz over Calcite $ 500 Jalgaon, Maharashtra State, India cabinet - 10.5 x 4 x 2 cm ![]() ![]() ![]() Laterally compressed translucent white Calcite crystal completely covered by a layer of sugary Quartz crystals, with attached pink Stilbite crystals. Unusual specimen that is reminiscent of Steve Smale's specimen known as 'The Cricket Bat' (see page 117 of the Smale Collection book). A couple of the Stilbite crystals are incomplete, otherwise undamaged, with the Stilbite only on one side. I've never seen another like this.
C633 - Silver $ 450 Batopilas, Chihuahua, Mexico small cabinet - 7 x 6 x 5.5 cm ![]() ![]() ![]() ![]() Vein of white Calcite loaded with crytalline Silver with lots of exposed Silver crystals on top. The Silver is present all throughout the Calcite, top to bottom. Out of an old collection from the 1970s.
C634 - Silver $ 650 Batopilas, Chihuahua, Mexico small cabinet - 7 x 6 x 5.5 cm ![]() ![]() ![]() ![]() Vein of white Calcite loaded with crytalline Silver with lots of exposed Silver crystals on top. The Silver is present all throughout the Calcite, top to bottom. Out of an old collection from the 1970s.
C637 - Prehnite $ 1200 Merelani Hills, Arusha, Tanzania small cabinet - 8 x 3.5 x 3 cm ![]() ![]() ![]() ![]() Along with many other 'world's best of species', Merelani produces the world's best Prehnites (in my opinion). This fantastic specimen is a complete undamaged floater that looks like it was constructed by dropping little grains of Prehnite atop each other until they formed this tall stack of crystals. The rear bottom is black from inclusions of Graphite, and there are Laumontite crystals included on one side near the base. One of the best Merelani yellow Prehnites I've owned.
C638 - Prehnite $ 600 Merelani Hills, Arusha, Tanzania miniature - 4.5 x 3 x 2 cm ![]() ![]() ![]() ![]() Outstanding, undamaged cluster of blue Prehnite, crystallized front and back. Rarely do you see blue Prehnites of this quality with such good crystal form. These are also color change, producing different shades of blue in indoor versus outdoor lighting.
C642 - Brucite $ 400 Killa Saifullah, Balochistan, Pakistan small cabinet - 8 x 7 x 3.5 cm ![]() ![]() ![]() ![]() Large, solid radial mass of Brucite on matrix. This is an uncommon example well crystallized all around, characteristic of open pocket growth and not growth in tight, contacted seams as are most. Translucent, thick and sturdy.
SM363 - Smithsonite replacing Calcite $ 250 San Antonio Mine, Chihuahua, Mexico cabinet - 12.0 x 9.0 x 4.6 cm ![]() ![]() ![]() ![]() ![]() The specimen shown is a specimen that has a thin layer of yellow Smithsonite crystals covering pseudomorphed scalenohedral Calcite crystals. It's an aesthetic example of a multi-generation pseudomorph with interesting internal crystal structure showing the original Calcite crystals completely replaced with some other species, then Smithsonite covering all.
SM395 - Cadmium Smithsonite $ 120 Mapimi, Durango, Mexico cabinet - 13.4 x 7.0 x 3.7 cm ![]() ![]() ![]() ![]() This rare variety of yellow color Smithsonite is known as 'Cadmium Smithsonite'. The element Cadmium gives it this color. These are uncommon at Mapimi and this was the best one out of only a small handful available. It is damage free with only minor contact at the edges where it was separated from matrix. A must for a complete Mapimi suite.
SM590 - Chrysocolla ps. after Selenite(?) $ 200 Lupoto Mine, Lubumbashi, Katanga Copper Crescent, Shaba, D.R. of Congo small cabinet - 6.6 x 5.4 x 3.0 cm ![]() ![]() ![]() ![]() Sky-blue Chrysocolla has replaced another species (possibly elongated Selenite crystals) in this pseudomorph specimen. A couple of the longer, large crystals that are incomplete show the replacement is total Chrysocolla.
SM592 - Wulfenite $ 150 San Francisco Mine, Sonora, Mexico small cabinet - 9.0 x 4.6 x 3.5 cm ![]() ![]() ![]() ![]() ![]() This specimen has literally hundreds of thin, flat, yellow-orange Wulfenite crystals on matrix with a dusting of lighter color micro Mimetite crystals on selective faces. It's a classic San Francisco Mine example. All the specimens from this mine are delicate, so it's normal for a few crystals to be incomplete. Overall, a very nice larger example from the locality. Ex. Rocksmiths Minerals.
SM593 - Cerussite $ 200 Yangshuo, Guangxi Region, China miniature - 4.7 x 4.0 x 1.5 cm ![]() ![]() ![]() ![]() A solid V-shaped grouping of lemon-yellow/peach color Cerussite crystals from Yangshuo. It's a superb example with only one crystal showing contact, otherwise near perfect. A most pleasing combination of high luster, sharply terminated crystals, and beautiful color transition.
SM598 - Wulfenite $ 400 Erupcion-Ahumada Mine, Sierra de Los Lamentos, Chihuahua, Mexico small cabinet - 8 x 4.5 x 3.9 cm ![]() ![]() ![]() ![]() ![]() Classic Wulfenite specimen with pseudo-cubic, tabular crystals from Los Lamentos, Mexico. Examples from Los Lamentos are considered to be among the finest of the species in the world. This old-timer was probably mined in the 1950's-1960's and the crystals have a very aesthetic chocolate brown/orange, sandwich-like, color zoning. The largest crystal in the group measures 3.1cm wide, considered large for the species. Minimal chipping here and there with only very minor contact. A significant large crystal specimen out of an old collection and offered now for the first time since the 1970s.
