These Necklaces are hand put together with genuine gemstones! The Gemstone was made into a pendant, held together with 925 Silver, hanging on a black silky smooth cord with an extender! Turquoise is perhaps the oldest stone in man's history, the talisman of kings, shamans, and warriors. It is a stone of protection, strong and opaque, yet soothing to the touch, healing to the eye, as if carved from an azure heaven and slipped to earth. 💙
