Lose yourself in a sea of color with this stunning gemstone beaded necklace, featuring faceted roundels of rich purple amethyst giving way to clustered teardrop shapes of blue-violet tanzanite along the lower curve. The royal color of the amethyst beads brings out the fine trace of purple in the gorgeous tanzanite gemstones. This 17-inch necklace is finished with a traditional lobster-claw clasp, in 14/20 yellow gold fill.
