Black Mica Bracelet

Black Mica, also known as Biotite, is a phyllosilicate mineral within the mica family. It typically forms in scales or layers, resembling books or parallel sheets stacked together. This mineral is often found alongside Yellow Tourmaline and within potassium Feldspar matrices. Black Mica's size can vary from microscopic to several inches in diameter, with its thickness dependent on the natural stacking of its sheets. Discovered in 1847, Black Mica was named to honor Jean Baptiste Biot, a renowned French physicist recognized for his extensive research on the optical properties of micas.
