Princess Cut Lab-Grown Diamond Vintage Engagement Rings in Platinum Under £3,500
Princess Cut Lab-Grown Diamond Vintage Engagement Rings in Platinum Under £3,500
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.
At £3,500 you can choose a 1.5ct lab-grown diamond in a premium setting, or step into natural diamonds with a 0.7ct stone in solitaire or halo. A versatile budget that opens both paths.
The platinum premium is more than offset by lab-grown diamond savings — delivering luxury without compromise.
Vintage rings with a 1ct lab-grown diamond start from £4,022
At 1ct, even lab-grown vintage rings start above £3,500.
