HARDYSTONITE, WILLEMITE
Franklin, NJ
$75.00
Click here to order by check or money order ...
Massive hardystonite showing typical greasy luster with willemite,
franklinite and brown, platy diopside of the type known in Franklin
as "zinc schefferite", a discredited but useful name. Willemite ex-
solution causes an attractive "outline" effect under short-wave ultra-
violet light. The brightness of the willemite fluorescence results in
some overexposure. Minor clinohedrite can be seen on the piece.
Specimen size - approx 14.5 cm. X 8 cm. X 6 cm.

BUSTAMITE, HARDYSTONITE, CLINOHEDRITE
Franklin, NJ
$450.00
Click here to order by check or money order ...
Massive pink bustamite with hardystonite and clinohedrite. These short
wave ultraviolet pictures are somewhat overexposed. The specimen is not
as vivid in real life. Even so, it is impressive and this material is hard to
find. The hardystonite is unusually bright. On top of that, this bustamite
has a tugtupite look under long-wave ultraviolet.
Specimen size - approx 15.5 cm. X 8.5 cm. X 7 cm.
