Abstract
The back portion of an omega-back earring is formed by investment casting and then heat-treated to have spring gold characteristics. A rear surface of the ornamental front portion of the earring includes a depression to present a concave profile which is complementary to the convex profile of the pushing part of the rear portion of the earring. In a non-identical mirror-image pair of earrings, a design element such as a small precious stone is provided on only one of the earring pair, at an inconspicuous spot, to aid the wearer in distinguishing the right earring from the left earring.
