The Cyclopean Isles is a small volcanic archipelago off the coast of Aci Trezza, in the Etna volcanic complex. They are the type locality for the analcime species, which we can see in this specimen. This old time sample from the Freiberg Bergakademie shows us vacuoles with idiomorphic analcime crystals accompanied by colorless, well-defined thomsonite-Ca prisms those have grown on the analcime. The two labels give clear testimony to the antiquity of the specimen. A true mineralogical curiosity.

This sulphur crystal specimen comes from one of the most worldwide famous mine for this element in the province of Agrigento. Nowadays it is difficult to find crystals of this size and less with a reasonable price. It shows very well defined faces and typically rounded edges. The yellow color is very intense, bright and with a remarkable transparence. To add value to the sample we observe various bituminous inclusions into back side. Good size and gem quality.
