Willemite:
FL Green SW
Calcite: FL Red SW
Rhodonite (?): non-fl.
Andradite: non-fl.
Franklinite: non-fl.
This is one of the most interesting "red & green" pieces I've ever
found on the Buckwheat. I collected it in November 2005.
Notice the non-fluorescent crystal shapes in the willemite. In
daylight they're very hard to distinguish from the rest of the
rock. I believe this mineral to be rhodonite or some other
pyroxenoid, even though the daylight color is mostly dull gray (like
tephroite). If it were tephroite, there'd probably be willemite
exsolution lines or veinlets in it. However, I'm not sure if this
always must be the case.
The aesthetic qualities of a fluorescent specimen rely not only on what
glows, but also on what doesn't.
Specimen is about 3 3/8 inches across maximum dimension.
