Large, lustrous celestine crystals on native sulfur – La Grasta Mine, Sicily. An exceptional, large-scale specimen featuring celestine crystals on native sulfur, sourced from the La Grasta mine in Sicily (Italy). The most striking feature of this specimen is the presence of large, well-developed celestine crystals that possess an excellent natural luster. Their brilliant, reflective surfaces—complemented by a delicate, pale-blue hue—stand out magnificently against the intense yellow of the native sulfur, creating a particularly attractive and elegant contrast. Weighing 7.45 kg (16.42 lbs) and measuring up to 32 cm (12.60 inches) at its largest dimension, this is a truly imposing specimen with a powerful visual impact. Its size, combined with the highly lustrous celestine crystals, makes it an extraordinary display piece and an excellent example of the classic celestine-sulfur association for which Sicilian sulfur deposits are renowned. The specimen originates from an old Sicilian mineral collection, assembled over the course of several decades.
