Heart Shaped Lab-Grown Diamond Side Stone Engagement Rings in 18K Yellow Gold Under £1,500

Yellow gold with a lab-grown diamond creates a warm, vintage-inspired look at an accessible price point. The traditional warmth of yellow gold paired with the modern value of lab-grown creates a ring that honours heritage while embracing innovation.

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.

Warm, timeless, and universally flattering. 18K yellow gold contains 75% pure gold and has a rich, warm tone that has been the traditional choice for fine jewellery and engagement rings for centuries. Its natural colour will never fade or require re-plating.

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.

Yellow gold lab-grown rings offer the most traditional aesthetic at the most accessible price.
