Authentic Pandora Sterling Silver October Birthstone Droplet Ring with Dome Cut Opalescent Pink Crystal. Item #191012NOP. The month of October is represented by opalescent Pink Crystal on this Sterling Silver birthstone ring in the Droplets series The crystal's tender pink shade in iridescent color can be an air of tenderness and caring, which is illuminated with feminine flare with the new dome flower cut. I purchased this and another Pandora ring for my daughter quite some time ago, and she never wore either one of them. They've been sitting in her dresser drawer. The rings are basically new. The box is included with this ring. I also listed the other ring, the Authentic Pandora Sterling Silver Princess Tiara Crown Ring, if interested. Stamped P2 S925 ALE 54. Size 6.
