Why choose a round engagement ring with a lab grown diamond?

The round engagement ring is the most iconic of all styles, admired for its perfect symmetry and unmatched brilliance. This knife-edge design showcases a certified lab grown diamond, precision-cut to maximise fire and sparkle. Available in sizes from 1 carat to 3 carats and beyond, this round engagement ring is handmade in Hatton Garden, London, offering both timeless beauty and sustainable luxury.

What makes the knife-edge round engagement ring so sophisticated?

The knife-edge band features a subtle ridge through the centre, creating an angular, architectural profile that reflects light beautifully. This design draws attention to the diamond while giving the illusion of a larger stone. A knife-edge round engagement ring balances minimalist elegance with bold geometry, making it one of the most requested solitaire styles in London, and the UK.

Are lab grown diamonds real, ethical, and durable?

Absolutely! Our lab grown diamonds are chemically, physically, and optically identical to mined stones. Sometimes described as ethical diamonds, they offer the same brilliance, durability, and fire while being a more sustainable choice. Selecting a lab grown diamond round engagement ring means embracing both luxury and responsibility.
