Cabrerite is the synonym for the rare magnesium-rich variety of annabergite. This fine, old-time specimen is from the old mines of Laurium, Greece and features a well-placed vug richly lined with gemmy and lustrous, green cabrerite microcrystals. From an older collection and accompanied by a faded Wards label. The collection this came out of was a museum stash dating to prior to WW I.
