Description

Sharp gemmy crystal of glauberite with very good lustre and classical striations for prismatic developments. Free of damages!.

These crystals are not primary but diagenetic, they are found lining geodes, without halite (such as those in Villarubia de Santiago, the type locality), so these are very stable and less sensitive to air moisture.

I collected this specimen back in 2004 at the Consuelo Mine, that produced long ago the world best glauberite crystals during the short period it was exploited at the XIX Century, from 1880 to 1889.
