Twenty-two, sparkling full-cut diamonds come together with high-polished platinum to create this small, platinum diamond heart necklace! Having 1/8 carat t.w., the diamonds are prong-set in a lovely, heart shape that measures just under 3/8" in length. Suspended from a 16" platinum cable chain, this heart necklace is secured with a spring-ring clasp. To view this necklace in white gold, see our Small, White Gold Diamond Heart Necklace #2120.
