Specimen of Silver crystals from Batopilas. Not the typical 'herringbone' style for the locality, this is a dense mass of crystals, some showing platy, cubic crystals to 3mm. Ex. Chuck Trantham collection.

Large, complete dodecahedral crystal of Chlorite after Garnet. There is an indentation on the back face, otherwise it has perfect flat faces all around. Ex. Chuck Trantham collection acquired from Dyck's Minerals in 1987.

Pristine cluster of golden metallic Marcasite crystals on matrix. The crystal group is 3cm wide with individual twinned crystals to 1cm in size. I understand these were found between the mid 1970s and the mid 1980s and collecting here is now prohibited because the site is now a natural reserve. Ex. Chuck Trantham collection acquired from Al McGuinness with label.

Well terminated single crystal showing good red coloration on the sides.

Cluster of pink/purple color zoned Fluorite crystals. Excellent luster and transparency.

Double-terminated cluster of 'Indicolite' with deep blue color. One end shows cat's-eye growth and has an attached cluster of Lepidolite. Complete and undamaged. Weighs 76.3 grams.

Sharp crystals of blue Azurite intermixed with green crystals of Malachite after Azurite pseudomorphs on a light matrix with additional yellow/green mineralization. Undamaged crystals with pseudomorphs that reach 2.2cm, some of which are double-terminated.

Achtaragdite is a rare pseudomorph of a hydrogrossular-chlorite-carbonate mineral after what is believed to be Helvite. This is a little understood psuedo likely found many decades ago at the type locality for Grossular garnet in Siberia. It is a fine example with a well formed tetrahedron of the form of the former Helvite crystal. 

Glassy, colorless/white orthorhombic crystals of vuagnatite, a rare silicate mineral, on matrix. Collected by Chuck Trantham in 1982 and valued at that time at $100.
