Selenite Pendant NecklaceThis necklace features a beautiful teardrop shaped matte selenite gemstone pendant on our chocolate brown waterproof cord. It is fully adjustable with a backdrop sliding knot closure. The name "selenite" comes from the Greek word "Selene," meaning moon, reflecting its moon like glow and soft, pearly color. Selenite is quite soft, with a Mohs hardness of just 2. This means it can be easily scratched, so it should be handled with care to prevent damage.
