Biotite has arrived!

Biotite MineralWe are excited to offer the mineral biotite on our website now. Biotite is a common mica mineral that is black to brownish-black in color. This soft mineral forms as a “book” with super thin crystal pages. You can use your fingernail to flake apart the individual layers of the book. It is really cool so check it out!
