This is a great looking specimen featuring
very distinctive and lustrous crystals set among
sprays of Actinolite. The Actinolite is heaviest at the bottom but is present among the
crystals
at the very top as well. I've seen larger specimens of this material but this had the best
crystals.
From the Bouismas Mine, Bou Azzer District, Tazenakht,
Ouarzazate Province, Morocco.
Measures 3.5 cm by 2.2 cm by 1 cm in total size.

Unique specimen featuring flat Sulfur
crystals on sparkling drusy Quartz!
These appeared over a decade ago and I haven't seen
any since. The initial find must of been
quite small. This was one of the largest plates I could find when they first appeared from
China.
The Sulfur crystals are somewhat flat with shiny, glassy surfaces. Interesting and
attractive.

Prefecture, Hunan Province, China.
Measures 9.5 cm by 12 cm by 3.5 cm in total size.
