NJ61AL3: Spheroidal aggregates of very lustrous translucent lamellar Bavenite crystals on matrix, with Chlorite.
The specimen comes from the Carlos González Bargueño collection, whose label we will send to the buyer. Carlos was the one who first found these Bavenites and thanks to his work these extraordinary specimens were saved. The Bavenites from Valdeconejillos are somewhat different from the better known ones from the Venero I quarry.
