This beautiful necklace is contemporary and is signed Caviar, 925 and 750. I believe this beautiful piece is made by the famous Lagos. The necklace is fashioned from sterling silver and trimmed in 18k yellow gold. It is set with a beautiful, high quality moonstone that has a blue cast to it and almost looks like a star sapphire as it has a moon across the middle which moves when the stone is moved. The necklace measures 18 inches long, the center piece is 7/8 of an inch wide and the chain is 1/4 inch wide. This necklace weighs 44.1 grams.
