MZL29AO0: New for 2021 and, in all probability, the best known so far for the species. Imayoshiite occurs as numerous very sharp crystals, with a tabular shape and hexagonal outline, transparent, very lustrous and colorless to slightly yellow, which occur together with spheroidal growths of pink-orange Bultfonteinite, with small white fibrous coatings of a Shinichengite (this new mineral species was initially labeled as possible Tobermorite-Clinotobermorite), on Andradite matrix.
The specimen has been analyzed and we will send a copy of the analysis to the buyer.
