- Chalcostibite on Siderite
- Miniature, 6.0 x 3.9 x 3.6 cm
- Saint-Pons, Ubaye valley, Alpes-de-Haute-Provence, Provence-Alpes-Cote d'Azur, France
Superb, sharp chalcostibite crystals in a "bowtie" cluster atop matrix, make this one of the better ones I have seen for sale in recent years. This was found at what really is an old classic locality, but recently in a lucky find of the early 1990s. Most people consider these to be the best examples of their species, for display purposes.
