Nephrite
Ouen Island ophiolite, Ouen Island, Le Mont-Dore, Southern Province, New Caledonia, France
This specimen of nephrite from Ouen Island has been polished on this side to show the fineness of its grain size. This face is crossed by a whitish plagioclase band. The pale green to grass green colored rock is fine grained, but it is not jade in the mineralogical sense.
