This 14/20 yellow gold-filled square soldered-closed ring is an unusual and eye-catching addition to gold-filled designs. Connecting rings and drops slide to the corners, making the square into a diamond-shape. Use tight wraps or natural tension to keep the ring square. Closed rings have no opening and are ideal as attach rings for pendant designs, drop or dangle designs, or as connecting rings between fabricated or metal-formed links and components. A closed ring presents a strong, smooth finish with no joint and no need to solder.
