Iridescent Chalcopyrite on scalenohedral Calcite crystals from a one time find in China. The Chalcopyrite occurs on the outside of the crystals and also just under the surface of the Calcite. The iridescent colors range from gold to green to red. These were found back 2014 and have not been found since. Highly aesthetic specimen in great condition.

Rare large, clear Grossular garnets to 1 cm wide from the Jeffrey Mine in Canada. The crystals are mostly colorless and slightly yellow at the transparent corners. These white/clear crystals were always rare and now even more so since the mine is closed.

Sharp 1.5cm octahedral red Spinel crystal in white Calcite. Translucent and in great condition. From recent finds in Tanzania.

Gemmy purply red Spinel crystal from Tanzania. Translucent to transparent and in great condition with just a couple edge chips.

Transparent green/yellow Sphalerite crystals var. Cleophane on Quartz crystals. The crystal clusters are spherical in shape, reach 1.5cm in diameter and are transparent. Comes mounted on a Lucite display stand.

Azurite clusters to 1.1 cm wide in an unusual association with Quartz, Cerussite, and Chrysocolla from a little known locality in Mexico. Oddly, this specimen comes with a receipt from Shreve & Company (a jewelry store in San Francisco) dated 1970. The Azurite clusters are bright and lustrous and occur on both sides of specimen.

Bow-tie red Stilbite cluster on matrix from Nasik, India. Normally found in pink crystals, this red Stilbite is unusual in color and forms a 3.9cm cluster with another 1.9 cm individual crystal to the right side.  An uncommon looking, quality specimen that stands out from the thousands of Indian Stilbites.

Old specimen of doubly-terminated Quartz crystals atop Hematite crystals from New York. The Quartz are transparent and sit atop metallic bladed Hematite crystals that cover a matrix of massive Hematite. This is a historic specimen formerly in the collection of Thomas Edison (inventor of the light bulb). Edison purchased the specimen as part of the George Kunz collection in 1890. Here's a chance to own a piece of mineral collecting history. Comes with Edison's old label.

Sharp and lustrous Azurite crystal with a rare serrated habit. Tsumeb produced Azurite crystals in a wide range of habits, and this style is interesting and uncommon. The crystal is a uniform 5mm thick and a deep translucent blue when backit (see last photo). Ex. Carl Acosta collection.

Cluster of bright, metallic crystals of Stibnite from China. The cluster includes long crystals to 11cm in length. These are classics from the Wuning Mine.

Intergrown octahedrons of Copper that have almost completely replaced earlier crystals of Cuprite (just a small amount of the original Cuprite is visible). Complete all around and undamaged. Small areas of Silver are also present giving it added appeal. This is an exceptional specimen as most of these have a coarser appearance due to larger subcrystals of Copper. The smaller size of the Copper crystals on this specimen yields an overall much sharper looking crystal.

Lovely rosettes of Azurite from the famous Chessy mines of France. These mines are long closed and I understand these specimens were found in the 1800s. This specimen is composed of two attached clusters of gorgeous blue color. There are no points of contact, a complete floater and undamaged.

Cluster of bright, translucent, deep emerald green crystals of Dioptase from the Congo. Nothing but solid Dioptase without matrix, with individual crystals to 2cm!

Interesting bi-color Tourmaline from  Mwajanga, Tanzania.  The crystal is a transparent, deep rootbeer color in the lower half with a sharp change to silvery grey, cat's-eye at the top. These half normal/half cats-eye crystals were found once at this mine and are very distinctive. This is a good sized crystal from this find. Weighs 16.3 grams.

Good sized crystals of Whitlockite on matrix from the Type locality in Canada. The pearly, tabular crystals of Whitlockite reach 1.5cm in size. Associated minerals include Collinsite, deep green Kulanite, Arrojadite, and transparent Quartz crystals. Comes with an old Al Ordway collection label.

Fine quality single crystal of Malachite after Azurite from Milpillas. This truely looks more like a Malachite after Tanzanite than what it is - it has such an unusal shape. The single 3.5cm tall crystal is visually striking against the white matrix and in perfect condition. The chatoyancy of the velvety Malachite is wonderful with a uniform wave of light rolling up to the termination as you turn it in your hand. There is a small amount of remaining Azurite around the base of the crystal. Unique crystal that is by far the best pseudomorph from Milpillas I've ever owned.

Gem Tourmaline crystal recently mined from the famous St. Anne's Mine in the Karoi district of Zimbabwe. Fully terminated, complete, and undamaged. It's transparent top to bottom with a good medium green color over most of the crystal with a darker green (though still transparent) termination. The termination is multi-faceted and complex. Excellent quality Tourmaline, internally flawless. Weighs 6.92 grams.

Lavender crystals of Creedite from the Hall Mine in Nevada. Lustrous and transparent, high quality crystals.

Large single octahedral Scheelite crystal from China. There is a small amount of attached Muscovite on one side, otherwise it's all Scheelite. Undamaged with good transparency, especially at the tip.

Bright metallic grey crystals of Gersdorffite from Morocco.  Fine quality crystals of Gersdorffite and a great display specimn for the species with bright green Annabergite adding good color contrast.

Fine quality Hemimorphite specimen from an obscure locality in Utah. This is a floater specimen well crystalized all around with White Calcite crystals are present on one side. Lustrous and translucent, high quality crystals all around. Neat and uncommon locality specimen that comes with an old Don Olson label.

Fantastic single Chrome Tourmaline from Tanzania. 'Chrome Tourmaline' is a vanandium and chromium rich variety of the species Dravite. This crystal has 3 distinct color zones - a bright, vivid green at the termination, a darker green at the center, and a yellow green at the base. This is one of about 5 similar crystals I purchased years ago and I've never seen another similar since then. Weighs 35 grams.
