Dark aqua blue lucite in a light weight, perfect-sized hoop. These are slightly skinnier than the other tube hoop in jet I have listed. Skinny tube hoops are simple & retro. measures approximately just over 1" in diameter and 4mm in width. The last pic shows how these look on for scale, but are pictured in black.
Earrings are made with vintage lucite parts that were made in Rhode Island in the 1960's - early 80's by Best Plastics. We hand-set them with surgical steel earring posts and they have sturdy surgical steel/acrylic backings on them as well. Light-weight & fun to wear.
