A plate of lilac crystals up to .7cm generously covering the matrix with additional later growth stage CO3 fluorapatites (carbonate group substituting for some of the phosphate) scattered about. This combination makes for a wonder under LW as the CO3 apatites are vibrant orange while the lilac ones go yellow. A very choice example.
Locality: Foote Lithium Company Mine, Kings Mountain, Cleveland County, North Carolina
Composition: calcium fluorophosphate
