Probably one of the best celestine specimens I've seen in this locality. Very aerial, with really good size and showing well defined faces and edges. Honey color, intense with certain zoning and an excellent transparence. Facetted by the pinacoid and various rhombic prisms. The cavity is completely covered by small quartz crystals, brilliant, between hyaline to amethyst. A definitive first quality specimen from Azaila, nearly impossible to find.

Celestine specimens from Azaila are recognized in the mineralogical world for its beauty, intense color and richness of facets. In the area of Azaila-Lécera we can find good size nodules and nodular levels of silexites. Most of these nodules are compact, but at certain levels appear cavities with gypsum and quartz crystals (sometimes amethyst). In very few of these cavities we can find celestine crystals. Large crystals are usually imperfect. Today it is very difficult to get good specimens from this Aragonese locality.
