Mid Century 1.14 Old Cut Diamond & 0.68 Carat Ruby Five Stone Ring, circa 1955Such a pleasing ring. The line of five gemstones are, unusually for a five stone ring, all of the same dimensions, meaning this will be a super easy ring to stack. The trio of impressively white old mine cut diamonds (graded E to F colour) are inter spaced by a pair of glowing blood red rubies. Each gem is secured in a 18k white gold coronet collet, leading to a slim and tapering 18k white gold shank. Currently size P (UK) or 7 1 2 (US). Free sizing
