NE63X6: Spheroidal crystal of Bavenite with very sharp polycrystalline growths on its faces. It is very bright and is implanted on a Quartz matrix partially coated by Pyrite and chlorite and with a curiously added small crystal of purple Fluorite. The sample is from the Carlos González Bargueño collection, whose label we’ll send to the buyer. Carlos was the first to find these Bavenites and it was thanks to his labor that these extraordinary samples have been saved.
