Heart Shaped Lab-Grown Diamond Side Stone Engagement Rings in Platinum Under £1,500

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 heart shape is the most overtly romantic diamond cut — a modified brilliant with a distinctive cleft at the top. It requires exceptional cutting skill to achieve symmetrical proportions and balanced lobes. Heart shaped diamonds are a bold, meaningful choice for those who want their engagement ring to make a romantic statement.

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.

The £1,000–£1,500 range opens up a wonderful selection of lab-grown diamond engagement rings with larger centre stones and more setting options. This is one of the most popular budget ranges for couples choosing lab-grown diamonds.

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