Vintage butter yellow necklace & matching clip earrings

Matching set of butter yellow necklace and clip-on earrings. The exact age is not known, guessing 1950s based on the style. Round butter yellow man-made cabochon in a pale gold metal setting. The metal setting is a rounded square made up of four overlapping leaves. No damage to the necklace and earrings that I can see. The necklace is adjustable in length based on where you hook the clasp. Overall length of the necklace is 41 cm (16 inches). The earrings are 3 cm (1.25 inch) diameter. Comes with the vintage jewelry box that I got when I purchased them. The box is worn with a water stain on the front and signs of wear.
