A French, sterling, Art Nouveau Plique-a-jour necklace in the Rene Lalique taste, circa 1900. The necklace features a citrine, marcasites and a natural pearl drop. Plique-a-jour translates to 'letting in daylight' and is a technique used in fine jewellery in the Art Nouveau period. The technique is enamelling without a backing, allowing the light to pass through the surface. The most covetable pieces of Plique-a-jour jewellery are by Rene Lalique. This particular necklace is marked 'sterling', with a butterfly mark which is likely the maker, and 'depose' meaning it has been registered or had a patent applied in France.
Length - approximately 52cm - with the option of shortening.
