I recently acquired a batch of this rare mineral, so it should be available here soon.
Like all new products, it deserves a little debriefing :)
Formula: Pb3CaAl(Si5O14)(OH)3 - 3H2O
Crystal System: Trigonal
Name: Named for the Shijiangshan mine, China, the type locality.
Type locality: Shijiangshan mine (Dashishan mine), Hexigten Banner (Keshiketeng Co.), Chifeng City (Ulanhad League; Chifeng Prefecture), Inner Mongolia, China
This mineral was approved by the IMA in 2022 and since then, few samples have been on sale.
All we can do now is wait :)
See you soon! Elise
