SM516 - Pyrite $ 600 (=~ AUS$ 937) 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.
C631 - Stilbite on Quartz over Calcite $ 500 (=~ AUS$ 781) 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 (=~ AUS$ 703) 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.

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 (=~ AUS$ 624) 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.

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 (=~ AUS$ 312) 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.
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 that is over 20 years old. A very clean specimen with only minor contact or chipping to the main crystals.
SM615 - Axinite on Quartz $ 240 (=~ AUS$ 375) 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.
SM552 - Carrolite $ 150 (=~ AUS$ 234) Kamoya South Mine, Kambove, Katanga, Congo small cabinet - 5.2 x 2.5 x 2.5 cm ![]() ![]() ![]() ![]() Mirror-lustrous octahedral Carrollite crystals to 1.8cm on matrix with white Calcite. From older finds out of an old collection.

Sold to me as Zircon replacing Siderite crystals, of which there are 3 distinct crystals to 2cm. An outstanding combination of species for the locality and in very good condition all-around.
