Lab-Grown Diamond Engagement Rings Under £3,500

Handcrafted · Hatton Garden, London

Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. They have the same crystal structure, hardness (10 on the Mohs scale), refractive index, and thermal conductivity. The only difference is their origin — grown in a controlled laboratory environment in 6–10 weeks rather than formed over billions of years. Lab-grown diamonds are typically 60–80% less expensive than equivalent natural diamonds, allowing you to choose a larger, higher-quality stone within your budget.

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.
