“Spark” Single Diamond Halo Cluster Ring

Price from

£1,945.00 – £4,080.00

Diamonds around a diamond – what could be a better idea! The end effect is to make the centre stone look larger and create more sparkle. The Spark puts larger diamonds around the centre than the Shimmer ring. It looks fantastic with a diamond and also spectacular around a coloured stone. A perfect engagement ring or dress ring.
