Marbled lucite hoop earrings measuring just about 1.25" or 29mm in diameter and 9mm in width. Each earring will vary in design as the agate pattern shows the varied plastic when it was cut from its drawn cane when the components were made. Check out the last pic where you can see the look & feel of this style on a model.
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.
