Creamy imitation mabe' pearl earrings feature a shiny gold plated setting and adjustable backs. They are each signed on the reverse as shown on an oval cartouche. Adjustable screwback earrings were first used by Napier in 1965; this design continued in use until 1999. Each measures 1 1/4 inches in length by almost an inch wide. Condition is fine with no issues; the nacre is perfect.
