EPF67AN8: Imayoshiite with Bultfonteinite, Shinichengite and Andradite

A novelty in the summer of 2021 and, in all likelihood, the best known for the species thus far. Imayoshiite occurs in numerous very sharp crystals, with a tabular habit and hexagonal outline, transparent, very lustrous and colorless to slightly yellow, associated with spheroidal growths of pinkish Bultfonteinite, with small white fibrous coatings of Shinichengite (this new mineral species was initially labeled as possible Tobermorite-Clinotobermorite) and on an Andradite matrix. The specimens have been analyzed and we will send a copy of the analysis to the buyer. To learn more about this species and the rest of the paragenesis discovered so far in this mine, it is essential to read the article 'Rare Borate Minerals from the Shijiangshan-Shalonggou Deposits, Hexigten Banner, Inner Mongolia, China' whose authors are César Menor-Salván, Berthold Ottens and Ed Richard, featured in Rock & Minerals magazine of September/October 2021, volume 96, number 5

MFR6AP3: Imayoshiite with Sphalerite, Shinichengite and Calcite

One of the best, if not the best, Imayoshiite of very large size, coming from the 2021 finds that yielded the best known so far for the species.

SV2980NRF: Kermesite with Quartz, Chalcopyrite and Stibnite

A classic of German mineralogy formed by fans of radiating Kermesite crystals of an intense crimson-red color, with a strong color contrast thanks to being deposited on snow-white Quartz crystals, on a rock matrix.
