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.

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.
