Fought over for centuries, the stone of queens and goddesses, the diamond never fails to excite and fascinate. Here is Swarovski's version in the form of the gold-foiled black diamond rivoli. This sweet little clasp has a 16 mm centerpiece, just big enough for bling, but not so big that it overpowers. The clasp is 28 mm from ring to ring. The centerpiece is vintage and is set in a hand-made sterling silver box clasp.
