A contemporary three carat oval lab diamond engagement ring designed not just to be beautiful alone — but to be perfect with the rings that follow it.

This certificated three carat oval lab grown diamond is set in platinum with four secure claws. The diamond is positioned lengthways along the finger, rather than across it, creating an elegant, elongating silhouette that feels both modern and timeless.

Graded:

Excellent Cut
D Colour
VS1 Clarity

This is a diamond chosen for light performance as much as presence — offering exceptional brilliance with a refined, balanced outline.

Designed to Sit with a Straight Wedding Ring

The setting has been carefully engineered so that a straight wedding ring can sit neatly beside it.

There is no need for a curved or shaped band. Instead, the clean profile of the setting allows your wedding ring — whether plain, diamond set, or eternity style — to rest comfortably alongside your engagement ring.

This ring is shown here styled with two of our Asymmetric Diamond Guard Wedding Rings, worn one on either side, to demonstrate how beautifully it pairs with a straight diamond band.

It can also be worn with many of our other wedding ring styles, including:

Plain platinum or gold bands
Diamond set wedding rings
Full or half eternity rings

Allowing you to create a combination that reflects your own way of wearing and marking this moment.
