18ct Gold Diamond & Opal Edwardian Rectangle RingAn 18ct gold Edwardian ring featuring a central rectangular shaped opal and bordered with a scalloped platinum edge containing fourteen sparkling diamonds. This ring is a real enchanting piece due to its age (made between 1901 1910) and the fiery opal which glows beautifully with vibrant flashes of colour including purple, green, blue, pink, orange and yellow. It's also much rarer to find a rectangular opal and diamond antique style. Size N.
