Engagement Rings
A promise, made singular. Exceptional diamonds, individually chosen. Settings composed to honour each stone. Finished by hand in London, every Astrea engagement ring is a singular expression of one of life’s most important promises.
Lab grown diamond engagement rings, made to order in London
An engagement ring is chosen once and worn for decades, which is why we make each one to order rather than from stock. You begin with the stone: round brilliant, oval, pear, emerald or cushion, every one a lab grown diamond with its own IGI certificate stating cut, colour and clarity. Then the setting — solitaire, hidden halo, three stone or trilogy — and the metal, in 18ct white, yellow or rose gold, or platinum.
Because the stones are grown rather than mined, the same budget buys a noticeably larger and cleaner diamond, with a documented origin. Most rings leave the atelier within three to four weeks, arrive in Astrea packaging with their certificate, and can be resized, re-polished and re-set for life. Book a private appointment in London or a video viewing from anywhere, and a client adviser will guide the choice with no obligation to buy.
