Semi-precious seraphinite beads are a beautiful chatoyant green. Seraphinite (sometimes mispelled seraphanite) is a specific type of clinochlore gemstone, and a member of the chlorite group (a group of phyllosilicate minerals).
This gemstone is said to be named for the shimmering feather-like markings that are typical on its polished surface (the word Seraph is found in Isaiah 6 of the Hebrew Testament, and refers to winged angels).
Seraphinite beads vary from dark green to gray-green in color, with chatoyance. They have a hardness between 2 and 4 on the Mohs scale of mineral hardness. Russian mineralogist Nikolay Koksharov is typically credited with discovering this pretty semiprecious gemstone. Seraphinite is mined in eastern Siberia, Russia.
