This kind of specimens are which make the love for minerals is being reinforced. In this piece, three very interesting magnesium species, two hydroxilcarbonates and one hydroxide coexist. On the one hand we observe some aesthetic and brilliant aggregates of foliaceous crystals of dypingite, forming rosettes, of intense white color, although they are colorless. They are accompanied by sheaves of flattened crystals of hydromagnesite, between translucent to transparent, colorless (they are similar to aragonite). All of them are disposed on a rock matrix covered with a layer with botrioidal forms, from blue to gray, of brucite. A Catalan piece that is hard to find today, with unusual species and quality.
