Seraphinite

saf-ahyuh r

Seraphinite was named after Seraphim, the highest rank of angels in the Bible, due to the feather-like appearance of its chatoyant fibers. The stone usually has a dark green to gray color with silvery shimmer caused by mica inclusions. This unique, somewhat mystic-looking gem is often used for carvings, decorative pieces and cut as cabochons.
