This is such a pretty necklace! The natural seed pearls are approximately 2mm and they are interspaced with Siberian amethysts that are oval and fully faceted. The amethysts are are a beautiful colour and range in size from 9mm by 13mm to 14mm by 18mm. The amethysts are top drilled twice and wire has been inserted so that they can hang. The necklace is 16 inches long and the ends are 10k. This piece has been recently restrung for security. This is a real keepsake! C. 1850.
