This necklace is rare because the center stone from the main medallion has a high inclined that is unique and quite frankly rare. The stone in the back is flat yet the top of the stone has this high pique. The stone is nestled in a silver braid. There is a special workmanship, the two blue stones that are in the chain sit in silver tone frames. Its closure, its typical slide safety clasp. The chain, not counting the medallion, runs 16”, and the medallion drop is 2-1/4” long. This necklace is in excellent vintage condition.
