About Yttrocerite
Formula:
(Ca,Y,Ce)F2+x
Colour:
Blue, reddish
Lustre:
Vitreous
Hardness:
4 - 5
Crystal System:
Isometric
Name:
Named from its chemical composition containing yttrium (named after Ytterby, Sweden) and cerium (named after the asteroid Ceres).
A variety of Fluorite
Y-rich fluorite (see also yttrofluorite). Note: A great many occurrences of yttrocerite reported in the nineteenth century were false. The so-called "yttrocerite" has repeatedly been shown to be ordinary purple fluorite without enrichment of rare earth elements.
