P637 - Fluorite $ 2200 Minggang Mine, Shihe District, Xinyang, Henan, China small cabinet - 8 x 5.5 x 2.5 cm
Isolated hemispheres of green Fluorite on a white Calcite matrix. The Hemispherical mounds of Fluorite reach 3cm in diameter and while having an overall rounded form, show cubic faces upon close inspection. The Fluorite are undamaged, translucent, with a saurated medium green color. This mine is known for large, purple globular Fluorite and these green Fluorite specimens were rare, possibly from a single find, and this is the nicest one of this style I've seen. Aesthetic and unusual old specimen from the Paul Geffner collection.
P638 - Grossular $ 850 Jeffrey Mine, Val-des-Sources, Quebec, Canada miniature - 4.5 x 3 x 2.5 cm

P639 - Celestite $ 1800 Sakoany deposit, Mitsinjo District, Boeny, Madagascar small cabinet - 7 x 6.5 x 6 cm

The main crystal is 4.5cm tall, transparent, and perfect. Note that the only contact is on the side of a back crystal as seen in photos, and although this crystal has a more flat than pointy termination, it is a good undamaged termination. Visually striking specimen from the Paul Geffner collection.
