Yellow scalenohedral Calcite crystals, each with sharp phantoms, possibly partially due to Cinnabar. This is a rare specimen from the old mercury mining district of Terlingua, located near the Mexican border. Cinnabar was discovered here in the 1880s, creating a temporary mining town, now nothing remains but a ghost town. This specimen is out of an old collection from the 1970s and comes with an old Fraziers Mineral label. A little bit of tip damage but overall in great condition.

Group of Copper crystals coated by Cuprite. The Cuprite covers most of the surface of the Copper and is crystallized in areas. There is also black Heterogenite and green Malachite present in areas. Large and colorful Copper specimen found in 2018.

A display specimen of white Calcite crystals hosting a few dark black Hematite crystal groups from this classic locality. An older example from The Charlie Key Collection disbursed a number of years ago. One old label shows a former price of $600. Lots of lustrous, clear and undamaged Calcite crystals and I can only find a couple missing along the back edge.

Here's an old English classic that features a large 1.8cm 'ball' of tan color Siderite crystals on a contrasting darker matrix of Cookeite from Cornwall. A very clean, aesthetic old-timer with numerous provenance labels including William Severance, Carter Rich, and Arnold Fisher. An old Trinity Minerals label shows a price of $300.

This specimen has water-clear fluorite crystals positioned on massive white calcite. A few grey-black galena crystals and some very minor micro pyrite crystals are also in association. The calcite surfaces are smooth showing some evidence of etching. Ex. Frazier's Minerals.

Sharp lustrous scorodite crystals to 8mm, intergrwon with bright golden pyrites. The crystals from slightly translucent blue to darker, almost black.

A plate-like matrix of water-clear quartz crystals showing an excellent example of a rare gwindel habit group measuring about 2.8cm tall on the right side. Nearly perfect with only minimal contact, mainly at the edges on the back side and difficult to see. A classic Swiss specimen.

Octahedral crystals of Gersdorffite, a nickel arsenic sulfide, on matrix with green Annabergite. Crystals reach 2.4cm wide.

Large arborescent group of Copper crystals coated by Cuprite. The Cuprite covers a majority of the surface of the Copper. There is also black Heterogenite and green Malachite present in areas. Large and colorful Copper specimen found in 2018.

Large, tapering Quartz crystal with interesting inclusions. The is one of the best, largest crystal from the one and only parcel I've ever seen of this material. The core is filled with hair-like crystals and green, yellow and red coloration. The outer zone is transparent to translucent. Complete and undamaged.

Small black crystals of Murdochite, a lead copper oxide, on crystals of Quartz. 

Large specimen of Amethyst with white scalenohedral Calcite crystals. Showy and undamaged.

54 specimens of Amethyst, many of them scepters. Specimen sizes are generally 1 to 2 cm in size. For reference, each box is 2.7cm square, and the entire flat is 18 x 26cm.

Cluster of deep green, terminated Tremolite crystals. Partially double-terminated. Great color.

Sharp crystals of Veszelyite to 4mm in vugs in matrix. Lots and lots of Veszelyite crystals all over. Veszelyite is a rare phosphate mineral only found in a few places worldwide as collectable mineral specimens. These specimens have only been found in the past few years and are one of the more interesting mineral surprises from China. Bottom of specimen has been sawn flat to better show display angles.
