Half Carat Oval Diamond Ring w/ Yellow Gold Filigree.  This modern engagement ring features a .50 carat oval cut diamond.  The center diamond is flanked on each side by an accent diamond and sits on a bed of open metal work.  The negative space serves a dual purpose, both allowing light to refract from the stone and providing a unique design aspect.  Additional accent diamonds line the outer edges of the marquis shaped carriage and add a fine layer of sparkle.  Finished in a buttery polished yellow gold, this ring is perfect for somebody looking for a wider ring!
