It is rare to find Munsteiner gems on the secondary market, so this circa 1990's ring is a find: a petite deep green gem tourmaline, 0.97 ct and angled like a lightning bolt, is set alongside channel-set diamonds and a pentagonal-cut pink tourmaline in an 18K gold polished setting not from the Munsteiner studio, that captures some of the geometric beauty of the gems themselves. Size 6.5, one sizing free with purchase.
