This is a wonderful seed pearl necklace. The pearls drape so beautifully in their festoon style with 5 strands. The blue enamel clasp , verre eglomise, is resplendent with pearls. The pearls are also gathered at the back with a beautiful 18 gold spacer. Because of it's shape it's very hard to measure. I measured it 14 and 1/2 inches long, but felt that could not be right. I put it on my neck (my neck measures 13 and 1/2) and it fit me perfectly with some drape and it wasn't even tight as a choker, so I am sure it would fit a neck measuring up to 14 and 1/2 inches. The necklace is circa 1880.
