Expansion bracelets, characterized by their elasticated bands, became popular in the mid-20th century, offering a comfortable and easy-to-wear alternative to traditional clasped jewelry. They were often adorned with various decorative elements, including glass beads, rhinestones, and faux pearls, making them accessible fashion accessories.

The "AB" or Aurora Borealis finish, applied to glass and crystal, creates a shimmering, iridescent effect that was highly fashionable from the 1950s onwards. This coating refracts light, producing a rainbow-like sheen that enhances the sparkle of the beads, making them appear more luxurious. Bracelets featuring this finish were common in costume jewelry of the era.
