Gypsum and Halite
Solno Mine, Inowrocław, Kujawsko-Pomorskie, Poland
6.5 x 4.4 x 3.8 cm (2.6 x 1.7 x 1. 5 inches)
Specimen status: Sold
A jackstraw cluster of gypsum blades,
transparent to opaque, decorated with colorless halite cubes. The
gypsum crystals are mostly terminated, reach 3.6 cm in length, and are
a bit more brown (and a bit less orange) than the pictures suggest (on
my computer). The halites reach about 3 mm across. Some small bruises
and rubs on terminations as expected from a soft mineral, but otherwise
in very good condition. The Solno Mine was a salt mine, abandoned in
1989, and subsequently flooded.

Aragonite (variety Flos
Ferri)
Styrian Erzberg, Eisenerz, Styria, Austria
5.2 x 4.6 x 3.9 cm (2.0 x 1.8 x 1.5 inches)
Specimen status: Sold
A massive white calcium carbonate matrix
hosts a crown of somewhat curly 'flos ferri' aragonite. A few missing
terminations make this a specimen representative of this aragonite
variety, or of the locality. The style of the (somewhat abused)
accompanying Ward's Natural Science Establishment label probably dates
the specimen to the 1950's or 1960's.
