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

1 handcrafted design · Hatton Garden, London

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.

Three Stone rings with a 1ct lab-grown diamond start from £1,863

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