Bromian Chlorargyrite & Coronadite On Cerussite

Rare Mineral

Description Tabs

Description
Locality: 
Broken Hill, New South Wales, Australia
Size Range: 
Miniature (4.5-7 cm)
Size: 
6 × 4.2 × 3.3 cm
Description

Small micro crystals of bromian chlorargyrite up to 1mm, occur with coronadite on milky cerussite. The coronadite seems to have formed little pods in the cerussite.

This is an old Broken Hill specimen and hard to determine what part of the mine it came from, possibly the Proprietary or British Mine. The bromian chlorargyrite has been exposed to light over a long period of time and being photo sensitive has changed colour from yellow /green to a light tan brown. They are however still very sharp, well formed crystals.
