Rich multi-colored Tourmaline faceted beads are joined with 18k gold beads with a center 18k gold and sapphire bead. Necklace has an 18k gold hook clasp. 16.5" length. Inspired by the Byzantine era, one of my favorite periods! Tourmaline is considered a precious gemstone by many, similar in category to sapphires, emeralds and rubies. Metaphysically, Touramaline is known as a powerful general healing stone. Depending on the color, it relates to the different chakras. Multi-color Tourmaline will therefore be effective on all the chakras.
