Stackable Green Glass Silver Bracelets Chunky

Set of 4 chunky bracelets made with glass and silver tone beads. Band is stretchy so it will fit nearly everyone. Glass beads are a yellowish green color. I do not know what type of metal the silver beads are. Could be worn all together, 2 on each wrist or one at a time and they will look great for any occasion. Vintage, probably 1980s but I can't be certain of when they were made. No branding or markings.
