Bracelet Vintage 1960s Sterling Glass stones good Hallmarked by designer Mid Century Modernist three strand

This good unique bracelet has a hand hammered sterling silver clasp and sterling beads in between the cut glass smooth beads, they appear to be a gray purple. Hard to distinguish.
This bracelet is marked 925 along with the designer/hallmark. I don't know exactly who made it. I have had it for years and the person I got it from said she bought it in Europe in the mid 1960s from a jewelry store. Thats about all I know.
