Art Deco 1.70 Carat Old Mine Cut Diamond Engagement Ring, French, circa 1935

Old cut diamonds this white and bright are incredibly rare. This impressive stone has been graded by GIA as F colour, meaning it veritably glows with fire and life. The diamond is secured in a four claw collet with talon claws, leading to step-down shoulders set with six (three each side) eight-cut diamonds to a nicely chunky platinum shank. An absolute treasure of a ring.
