Goldtone and off white carved resin ring with inside adjuster. Marked "Trifari." Size 6 1/2 at the largest, though if you needed smaller it would work with the adjuster.  I believe this matches a pair of earrings which were advertised by Trifari in 1972. Measures: 5/8 inches tall by 7/8 inches wide by 1 3/16 inches deep. Condition: Very good; minor wear to interior.
