Signed by the modern designer Ippolita, this elegant long chain necklace is not particularly old, but it’s simply fabulous. Checkerboard- cut cabochons of transparent smoky quartz are backed on the reverse with reflective hematite cabochons, so light is bouncing both off and through the stones as they flip back and forth. Different sizes of framed gems float like bubbles along the 36” long chain, which can be worn long or doubled along the collarbone. 18k yellow gold, contemporary.
