Lab-Grown Melee Diamonds


Following the popularity of lab-grown diamonds, this year we introduced small lab-grown diamonds available to order from our UK showroom. Our lab-diamond melee includes a wide selection of diamond sizes available from stock, ranging from 1mm round brilliant cut diamonds up to 4.7mm round brilliant cut diamonds. All small lab-grown diamonds include reference to their lab-grown status and are available in one colour and clarity combination—G colour and VS clarity. Trade prices are available upon request for jewellers and goldsmiths.
