Item Description

A rich and colorful, two-sided miniature specimen of nadorite, a rare Pb-Sb oxyhalide. The thick side of the thin matrix crust is covered with crosshatched metallic blades, to a large 2.2 cm. Much smaller straw-yellow blades cover the other side, as a striking contrast. The very best examples of the species come from here. This ancient Type Locality was worked by the Romans for lead and zinc and later by the French and Algerians for antimony. Although many blades of the large crystal side are broken or show portions, there are also many good crystals mixed in and the overall richness is significant. The smaller yellow blades are in excellent shape. I am told that most of these were found during the French expeditionary times of the late 1800s and early 1900s, by the French colonial geological exploratory bureau BRGM (and have seen some such labels turn up on the market with nadorites, time to time, which confirms this). This TYPE LOCALITY is the only locality for superb larger crystals of this species. Ex A.G Moss Collection. Valued at $1500.
