Antique 14k Russian Art Nouveau Sapphire and Diamond Negligee Style Necklace
One of a kind, rare, antique Russian, hallmarked Art Nouveau necklace boasting amazing rose cut and old mine cut diamonds with a feature of dark "steel" blue sapphires. Necklace dates to around 1880 with hallmarks for 14k gold and Russian origin. A delicate, cable link chain with a barrel clasp closure holds the negligee style centre with articulated drops including several small diamonds on the stems and larger diamonds and pear shaped sapphire on the ends. Most negligee necklaces have only two drops and this particular, delightful piece adds extra character and sparkling dimension with one more.
