Art Deco 2.06 Carat Old Cut Diamond Engagement Ring, circa 1920A jaw droppingly beautiful Art Deco engagement ring. The old European cut diamond in the centre graded by IGI as E colour, SI2 clarity is almost impossibly white, bright and lively. The stone is secured in magnificent platinum mount; four split claws at compass points lead to a sweeping and detailing gallery, conforming to a slim, knife edge shank adorned with six (three each side) eight cut diamonds at the shoulders. Truly exceptional. Currently size
