This is a beautiful Edwardian necklace. The gold is not hallmarked but both the chain and the clasp tested 14K. There are natural Amethyst briolette drops. Above each Amethyst drop is a cultured freshwater pearl. There are 5 Amethyst and pearl drops. The necklace has great movement and the stones sparkle when worn. Total length is 15 1/2". The stones are graduated by a small amount so the largest Amethyst is at the bottom. Condition is very good for age. I would date this delicate and fine necklace at c1915.
