This is a wonderful three strand Blister Pearl beads necklace with a clasp marked 14k and a tiny hallmark I cant read necklace from a high end estate. The is 17" clasped and the average bead is 7mm by 9mm and when on neck form has a 1 3/4" center. The blister pearls are a stunning golden color. I assume they are dyed. Stunning and in nice condition. You should be pleased.  Thanks for looking.
