A mineralogical specimen of great freshness and excellent quality. Discovered at the Rivet quarry, in Peyrebrune, in the commune of Saint-Lieux-Lafenasse in the Tarn. Very beautiful calcites with an unusual elongated facies. They are shiny and often translucent, on a first growth of siderite. Only a few specimens have been found.
