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.
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.
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.
SM601 - Fluorite and Galena Naica, Chihuahua, Mexico large cabinet - 20.0 x 15.0 x 8.0 cm ![]() ![]() ![]() ![]() A beautiful, pristine condition, cabinet size specimen with clear, slightly modified, Fluorite crystals and Galena crystals. The clear translucent Fluorites have a light green intermixed coloration. An old label from 'Flying Pan Mineral Center' of Littleton, Colorado is included with a note on the back showing a price of $65 in 1980. A very well preserved specimen with the only visible damage seen at the peripheral edges of of the matrix. Specimen weight is approximately 7-9 lbs.
SM606 - Sphalerite with Quartz Pacococha, Huancavalica, Peru cabinet - 12.0 x 9.2 x 4.7 cm ![]() ![]() ![]() ![]() ![]() Large, dark color Sphalerite crystals dominate the top of this specimen with the largest individual one measuring 3.5cm on edge. The matrix is entirely Sphalerite with the terminated top crystals showing small white druzy Quartz crystals providing a nice contrast. Weight is 1lb, 10oz. Ex. The Rocksmiths Minerals with their old label showing $22 price over 20 years ago. A very clean specimen with only minor contact or chipping to the main crystals.
SM615 - Axinite on Quartz $ 240 Butte County, California, USA miniature - 4.0 x 2.0 x 1.5 cm ![]() ![]() ![]() A rare specimen from Butte County in California showing a cluster of bladed, light brown, Axinite crystals centered on a pair of water-clear Quartz crystals. The specimen is a floater with no point of attachment visible and the Quartz crystals are terminated on both ends. No visible damage to any part of this specimen. Murdoch, Joseph & Robert W. Webb (1966), in Minerals of California, notes an occurrence near the Feather River and Yankee Hill areas, but little else is known. Comes mounted with minreal tac in a 2-inch perky box with an original old faded label. A true rarity for the California collector.
SM623 - Calcite $ 200 North Vernon, Jennings County, Indiana, USA miniature - 4.0 x 3.0 x 2.6 cm ![]() ![]() ![]() A classic Vernon Calcite specimen with sharp, golden color, gemmy crystals on minor matrix.

A group of yellow-orange crystals with chisel terminations contrasts nicely with the dark matrix. Most specimens were crystal clusters without matrix.
