This is an enhancer you can wear alone or to jazz up a strand of pearls. The bail opens and then snaps securely shut. You can also wear it with one of our Byzantine chain necklaces or our Roman weave necklaces with gold floaters. The green amethyst shown here is 15mm long and set in the gold cap are rhodalite garnets ( one in the front and one on back). The enhancer itself is encrusted with tiny full cut diamonds.
