The name "astrophylite" is derived from the Greek words "astron" meaning "star" and "phyllon" meaning "leaf". Our Astrophylite beads are a dark, velvety black with glittering streaks of silvery-gray. This is a very dramatic looking gemstone! You can see the naturally occurring "bladed crystals" shimmering within the stones. This awesome effect is difficult to capture on camera, but when they're around your neck, they're beautiful!
