Vintage NWT Black Onyx Cabochon Cluster Ring 18k Yellow Gold Electroplate

This is a vintage ring, but new old stock; it's never been worn or sold before. It features black onyx and cubic zirconia stones in a cluster. There are five onyx cabochons semi-precious gemstones, and four round cut cubic zirconia stones. The stones are set in 18k yellow gold electroplate. The ring is signed "DO", the hallmark for Dolphin Ore, an Israeli-based jeweler that was well-known for its high-quality, nickel-free, gold-plated jewelry in the 1990s.
