This appears to be a vintage rhinestone tennis bracelet or short necklace featuring prong-set blue chaton crystals in a dark gunmetal or pot metal setting, accented with larger purple marquise (navette) cut stones at the clasp end. This beautiful bracelet is very sparkly and in excellent condition!! Comes from a smoke free, pet friendly home.
