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.

Specimen of Almandine garnet crystals in schist matrix from the well known Wrangell Island locality in Alaska. The crystals reach 1.5cm wide with purple/red coloration and translucency and are well exposed from the schist. This one is loaded with crystals - the collector must have been very happy to find this one with 5 good crystals in one small piece of schist. A USA classic.

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.

Glassy and gemmy single Tanzanite crystal with an elongated, unusual form. It's somewhat triangular in cross-section, natural and unheated. Fine and undamaged and a good value for this size and quality.

Cluster of bright, translucent, deep emerald green crystals of Dioptase from the Congo. Nothing but solid Dioptase without matrix, with individual crystals to 1.6cm.

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.

Emerald green crystals of Dioptase from the Congo. A fine thumbnail composed of a single large crystal with a smaller doubly-terminated crystal attached to the side.
