Princess Cut Lab-Grown Diamond Side Stone Engagement Rings in Platinum Under £2,000

Platinum and lab-grown diamonds together represent the pinnacle of modern engagement ring design — the purest metal paired with the smartest diamond choice. Platinum's neutral white lets the lab-grown diamond's brilliance shine without colour interference.

The princess cut is a square or near-square brilliant-cut diamond that offers exceptional sparkle in a modern, geometric profile. It retains more rough diamond weight during cutting than a round brilliant, making it a strong value proposition without sacrificing fire or brilliance.

The purest choice for a lifetime of wear. Platinum is 95% pure, naturally white, and will never fade or yellow over time. It is denser and heavier than gold, giving your ring a satisfying weight and substance. Platinum is hypoallergenic, making it ideal for sensitive skin.

Under £2,000, you can find a 1ct lab-grown diamond engagement ring in your choice of metal and setting style. This price point represents the most popular budget for lab-grown diamond engagement rings — genuine luxury without compromise.

The platinum premium is more than offset by lab-grown diamond savings — delivering luxury without compromise.

Side Stone rings with a 1ct lab-grown diamond start from £2,037

At 1ct, even lab-grown side stone rings start above £2,000.
