ERT35AO0: Great piece, both for its size and its quality, being (in size) one of the best known fluorites from this deposit. The large cubes, with good transparency and a nice uniform green color, have inclusions and on some edges octahedral faces that can be distinguished from cleavages because they are somewhat rough and show crystal figures. Exceptional specimen from a historic mine.
Marsanges Mine, Pratclos (Pratclaux) vein, Langeac, Brioude, Haute-Loire, Auvergne-Rhône-Alpes  France

Specimen size: 23.5 × 13.5 × 15.5 cm = 9.25” × 5.31” × 6.10”

Main crystal size: 8.9 × 8.3 cm = 3.50” × 3.27”

TDA86AO0: Stylized parallel growths of Gold crystals with a very well defined morphology, with the dominant forms of the octahedron in parallel growths and with a very marked spinel-law twin. The piece is very aesthetic and for this reason it has been given the nickname 'The flame' since its shape is reminiscent of a flame moved by the wind.The specimen has been published in the book 'Gold - monograph -', by Joaquim Callén, on page 17

MBR91AO0: A novelty for 2021. Shinichengite on matrix (this new mineral species was initially labeled as possible Tobermorite-Clinotobermorite) that forms small fibrous spheroidal intense pink coatings associated with spheroidal growths of orange-brown Bultfonteinite of good size, on matrix.
The specimen has been analyzed and we will send a copy of the analysis to the buyer.
