Shelley's Vintage Originals. The centerpiece of this brass charm necklace is a mobile of gray and purple crystals, a small brass unicorn, elephant, horse, and stars with a drop of an engraved brass heart. It measures 3 1/2" in length. The centerpiece hangs from a long four strand brass chain. The chain has a lobster claw clasp but will easily slip over your head without being unclasped. The necklace measures 28" in length and can be shortened per customer request.
