Tunellite
Tunellite is a rare borate mineral with the chemical formula strontium hexaborate hydroxide trihydrate. It belongs to the monoclinic crystal system and is classified in the Strunz system as 6.FC.05. This mineral exhibits a vitreous luster and typically appears white to colorless in color. Its hardness on the Mohs scale is not specified, but it is likely relatively soft given its hydrous nature. Tunellite has a low to moderate density and is part of the borate mineral group, which is known for its complex anionic structures and hydrous compositions.
