Description
A very attractive and colorful specimen and typical for Sardinia: A vug in a limonitic gossan matrix is lined with botryoidal, warty Hemimorphite crystals with a deep light blue color. An absolute classic from the Sa Duchessa Mine that worked Zinc mineralisations from 1872 until it was finally closed in the early 1970s after decades of inactivity due to the lack of ore reserves.
