We stumbled upon a sparkling stash of these vintage iridescent earrings at market a few weeks ago and were instantly charmed by the flashes of delight found in the beads. From brilliant pink to gorgeous green, the gray crystals give way to the most stunning of hues when the light hits their facets, and we knew immediately they'd need just the right setting to show them off.  That's when we remembered our matte-finished hematite beads in the studio--hefty (hematite is known for its substantial weight) but beautiful, they offer their subtlety of shade to the glittering gems at their side. A vintage silvertone clasp is adjustable from 20-22" at back, complete with a crystal chain that completes the look.
