EYT26AN8: 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.
