Very rich scholzite specimen, an unusual phosphate of Ca and Zn, with elongated prismatic crystals, transparence and brilliance. It comes from a classic Australian locality for the species as is the Martins Well area, about 40 miles SE as such indicates this old label. A zinc and phosphorus-rich deposit in dispirited breccia. It is as mined for a few years for mineral specimens (mostly scholzite). 233a1
If something I like about the world of selling minerals is to find specimens lost in the nooks of old collections. This sample is a case of this. It is an Australian piece, of good size, formed by a druse of ferro-axinite crystals, not very big, but with an excellent color and transparency. They are accompanied by calcite and curious milky quartz. The specimen comes from a locality located NW of Queenstown, Tasmania, a big skarn that was worked by their sulfides: pyrite, pyrrhotite, arsenopyrite, chalcopyrite. Under the calcite ferro-axinite appeared... But a long time ago.
This specimen is really interesting not only for the quality of the crystal but the locality it comes from. Few specimens are represented in collections. This sample shows a brilliant metallic luster and sharp faces and edges. Located in a gully, this locality consists of outcropping hydrothermally-altered and weathered Wooltana volcanics containing veins and pockets of zeolites, calcite and crystallised ilmenite.
Rich group of elongated prismatic crystals of crocoite with an intense orange to red color very characteristic for the species. Brilliant and partially covering the goethite and rocky matrix.
Specimens of this Australian locality are uncommon in the maket, but their beauty makes them stand out from the smoky quartz samples. It is very curious how these specimens nodules are found into rhyolitic matrix geodes called "thundereggs"; this vugs are usually covered by small milky quartz crystals, some amethyst... They are in themselves a treasure of Nature. In this specimen we see a group of very defined crystals, one doubly terminated. Excellent transparency and smoky color zoning. On matrix. A very aesthetic and elegant piece.

They are in themselves a treasure of Nature. In this specimen we offer we see a parallel growth, probably scepter, crossed with some crystals, one doubly terminated. Excellent transparency and smoky color zoning. On a small matrix. A very aesthetic and elegant piece.
