Leo De Vroomen 18K Yellow Gold Convertible Enameled Cultured South Sea Pearl, 1.00 CTW Diamond, and 3.64 CTW Tanzanite Earrings

Item Details

A pair of circa 1997 18K yellow gold cultured south sea pearl, diamond, and tanzanite enameled convertible earrings by London-based Dutch Goldsmith and designer, Leo De Vroomen. Each earring features a field of round brilliant cut diamonds to the top center, which meets fan-like fields with champlevé enamelwork in an orange and yellow pallet, with several layers being applied to create the gradient effect. The bottom center houses a buff top pear tanzanite, which has a cabochon table, and a faceted pavilion. Each earring is fitted with a detachable cultured South Sea pearl drop. De Vroomen is world renowned for his skill in various enameling techniques, for his use of finely crafted gold, fine South Sea and Tahitian pearls, and for seeking a unique color pallet for each piece. The pieces are finished with clutch back posts, which have been modified from their original clip backs.
