A splendid specimen of blue aurichalcite decorated with sparkling calcite from this uncommon locality - San Giovanni Mine, Iglesias, Sardinia, Italy. This is one very old specimen. It displays awesome rich turquoise-blue aurichalcite core beautifully decorated with white calcite crystals. The calcites are lustrous and strongly sparkling. The specimen shows on 360 degree. In excellent condition. On acrylic base.

Fascinating!
