Stunning drop collar design bib necklace

Drop chandelier, collar , bib statement necklace . Appears to faux pearls a red center stone with other colorless stones in as well. Made on rope with a beaded seed bead slider to pull it on high on chest or wear lower. Rare I could not find any markings or one like it . It shows wear stones all appear intact but a few are dirty looking like maybe glue used to make or just age . Stunning and would make a great collection piece to display or wear .
