1950s UK Vintage Pink Soviet Diamond Square Earrings

These vintage earrings, dating back to the 1950s in the UK, are crafted from 9k gold and feature cubic zirconia. Cubic zirconia was first discovered in 1892 and has been mass-produced synthetically since 1976. Its hardness, colorlessness, and optical flawlessness make it a popular diamond alternative. By adding different metal oxides to the raw material, crystals of various colors can be achieved. As this synthetic method was first invented and used in the Soviet Union, cubic zirconia is also known as "Soviet diamond" or "Soviet stone." The earrings showcase a substantial, full square setting with a delicate pink cubic zirconia at its center. The open-back setting enhances the gem's clarity and brilliance. The well-proportioned design lends an exquisite and sharp aesthetic to the piece. Designed as single earrings, they offer distinct character whether worn at a square or diamond orientation. The earrings are in good vintage condition, with normal signs of oxidation and wear consistent with vintage jewelry, not new items.
