This necklace is the most elaborate of its kind that I have had. Made of natural seed pearls hand sewn onto mother of pearl plaques, this is meant to wow! The necklace is 16 inches long and the largest plaques are 1 1/4 inches wide and 1 inch tall.. No pearls are missing and the necklace is in nice condition. C. 1800. This would of most likely been a wedding present to the bride!
