Heart Shaped Engagement Rings Under £3,500

19 handcrafted designs · Hatton Garden, London

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.

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.
