EEF77AN8: 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 shape and hexagonal outline, transparent, very lustrous and colorless, with small white fibrous coatings of Shinichengite (this new mineral species was initially labeled as possible Tobermorite-Clinotobermorite) and small Andradite crystals. An exceptional specimen, worthy of any Museum.
This specimen has been analyzed and we will send a copy of the analysis to the buyer.
