Dark orange-tan color (typical color for the locality) Ferrierite-(Mg) lines the inside of the vug on this attractive thumbnail specimen. You rarely see these on the market, and this is one has great color. These are some of the best in the world of the species. Ex Kay Robertson Collection (#10160).

A great thumbnail specimen of this rare material from Italy.
