Collection: Round Lab Grown Diamond Engagement Rings

Explore round lab grown diamond engagement rings, chosen for their timeless shape and outstanding sparkle. Discover elegant solitaire, halo, three stone and diamond-set designs in platinum and 18ct gold.

Explore round lab grown diamond engagement rings at Avanti Jewellers, featuring one of the most enduring and brilliant diamond shapes. With its carefully balanced facets and symmetrical outline, the round brilliant cut is designed to reflect light beautifully from every angle.

A round centre diamond suits an exceptional variety of engagement ring styles. Choose a refined solitaire for a timeless appearance, a halo setting for added sparkle or a three stone design that symbolises the past, present and future. Rings with diamond-set shoulders provide further brilliance while allowing the centre stone to remain the main focus.

Our collection includes round lab grown diamond engagement rings crafted in luxurious platinum and 18ct gold. Designs range from delicate four and six claw settings to elevated profiles that allow additional light to pass through the diamond. Yellow gold bands can also be paired with white metal settings, creating a traditional two-colour finish that beautifully frames the centre stone.

Lab grown diamonds possess the same physical, chemical and optical properties as natural diamonds. Their exceptional brilliance makes them an increasingly popular choice for couples seeking a beautifully proportioned diamond with greater flexibility around size and design.
