Gooseberries
Formula:
Ca3(Al,Cr3+)2(SiO4)3
Colour:
Green
Name:
The original grossular named "cinnamon stone" ("Kanelstein" in German) in 1803 by Abraham Gottlob Werner and renamed grossularite by Werner in 1808. Named for the colour of gooseberries (Ribes grossularium) as the original specimens were this colour.
Note: Chrome-bearing rather than chromian is the preferred adjectival modifier recommended by the IMA (Bayliss et al. 2005).

Green, more or less chrome-bearing to -rich variety of grossular, often confused with uvarovite.
