This beautiful ring is a vintage piece, but new old stock; it's never been worn or sold before. It features a large oval cabochon aventurine in a blue-green color. Aventurine is a semi-precious gemstone; it's a type of quartzite, and it's believed to be a lucky stone, bringing prosperity and wealth to the wearer. It's set in 18K gold electroplate, and it has the signature dolphin hallmark of Dolphin Ore, an Israeli jeweler that was well-known for its high-quality, nickel-free, gold-plated jewelry. Dolphin Ore made a name for itself for its jewelry that was inspired by major designers like Van Cleef & Arpsels, Cartier, Hattie Carnegie, Tiffany & Co, and Сarrеra y Cаrrera. Its luxurious costume pieces are high-quality, with a distinctive signature look. The ring will come in a gift box. Please note, aventurine, like many other semi-precious gemstones, has some mineral inclusions. No two stones are exactly the same, so expect some minor differences.
