Blue sapphire halo engagement ring set in a micro set diamond halo. This ring features a centre Oval cut Blue Sapphire surrounded by a halo of smaller round diamonds. Round diamonds are used to edge this Oval cut Sapphire: the look is dramatic with dazzling scintillation. The halo setting is a ring of small accent stones, typically pavé diamonds, that encircle a larger centre stone. The Halo engagement ring style gracefully accentuates the brilliance and size of the centre stone.
