Diamond three stone ring, circa 1925. This classic three-stone diamond ring is set with a substantial trio of early to mid-20th century circular-cut diamonds. With a centre stone weighing approximately 0.55 carats, and shoulder stones each weighing in at approximately 0.50 carats, the effect is a beautiful, glittering band of light across the finger. A beautiful engagement ring that would still sit perfectly alongside a wedding band, with a low profile on the hand – thanks to its beautiful handmade early to mid-20th century mount.
