Heart Shaped Lab-Grown Diamond Engagement Rings in 18K Rose Gold Under £3,500
19 handcrafted designs · Hatton Garden, London
Rose gold and lab-grown diamonds together create one of the most Instagram-worthy engagement ring combinations. The romantic blush of rose gold contrasts beautifully with a brilliant white lab-grown diamond.
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.
