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.

Vug completely filled by radial masses of light blue Hemimorphite crystals. Ex. Chuck Trantham collection. Undamaged.

Large, thick translucent crystals of yellow Prehnite. This is a great cluster of crystals with top color and crystal form. Despite a bit of chipping, it represents the best of Merelani Prehnite, considered among the best in the world.
