ILVAITE CRYSTALS SPECIMENS

Ilvaite is an iron and calcium sorosilicate that often contains manganese and magnesium impurities. It occurs in magnetite, zinc, and copper ore deposits, along with contact metamorphic deposits and zeolite zones. Ilvaite can be found as lustrous, radiating columnar crystals with striations, though it is typically unearthed in massive forms with indistinguishable crystal structures. It is named after the old Latin name of Elba Island ("Ilva"), where it was first described.

Well-formed ilvaite crystals have been collected from China, Russia, the United States, Italy, and Greece.
