Archimede Seguso the world renown handmade glass maker was commissioned by Coco Chanel to make a series of exquisite linked chain jewels. Coral colour glass were blown into Seguso's signature oval links, some enhanced with crystal roundel. Instead of original clasp it comes with a perfectly match ring clasp and you can hook on whatever length desired. You may also hook both ends by a brooch as a photo shown.  Chanel box included but not a original one from 60s.
