This pretty necklace is circa 1990s. The pendant is fashioned from various shades of lavender or purple pearls and carved green stones which may be jade. The metal is 18k white gold plated metal. The pendant measures 1 1/4 x 1 1/2 inches and the chain is 16 inches long. I love pearls of all types and felt lucky to be able to purchased four such necklaces from a woman, with various colored pearls. The condition is like new. The pearls are slightly baroque and are probably fresh water.
