Specimen of calcite with very aesthetic stalactitic forms. It comes from a locality not well represented in collections.

Hidalgoite specimen from this classic Spanish mine. It appears as olive-green coatings, forming aggregates of tiny crystals. Collected in 1999 by M. Marí and A. García. The Estrella mine is located in the Majadillas hill, in the extreme south of the municipality of Pardos, in Guadalajara. It is an old copper and silver mine whose exploitation dates back to the 17th century, with its maximum activity being in the mid-19th century coinciding with the splendor of the nearby Hiendelaencina mines.

Very curious specimen formed by several cubic crystals of halite, some with hoppered growth forms, bright and translucent. A very aesthetic neoformation of these "salinas" (saltworks). Although it is believed that the Romans, in the s. I AD, they already extracted salt from the area, the saltworks of Imón were built in the 10th century and have been exploited intermittently for centuries. In 2015 they returned to production with the construction of new pools of enormous dimensions.
