MD-199879 - Fluorite (Var: Yttrocerite) - - Archived Rockport Granite Company quarries, Rockport, Essex Co., Massachusetts, USA small cabinet, 6.9 x 3.7 x 1.8 cm.
6.9 x 3.7 x 1.8 cm. Yttrocerite is an odd blue/purplish calcium fluoride with yttrium and cerium. In other words, it is weird chemistry and here shows as purple splotches. Ex. Philadelphia Academy of Sciences Collection.
PAS-43 - Yttrocerite - $ 150 SOLD Rockport Granite Company quarry, Rockport, Essex Co., Massachusetts, USA small cabinet, 6.9 x 3.7 x 1.8 cm ex. Philadelphia Academy of Natural Sciences
Yttrocerite is an odd blue/purpley calcium fluoride withyttrium and cerium. In other words, it is weird chemistry and here shows as purple splotches (but richly so!). Mindat lists yttrocerite from this locality as tentative/unverified but reported. Well, apparently we finally have a piece pretty solidly linked to the quarry as I am sure the person owning this at the time would have known better than us today, over 100 years later.
