Astrea London is a jewellery maison specialising in lab-grown diamond jewellery, engagement rings and wedding bands. Founded on the belief that fine jewellery should be made without compromise, the brand uses diamonds grown rather than mined and selects stones for their clarity and character. Its diamonds and jewellery are independently certified by IGI, GCAL or GIA, and pieces are assay tested.

The collections include everyday and high jewellery, as well as designs in the Eternal, Roma, Luna, For Him and Sarah Jessica Parker ranges. Sarah Jessica Parker is a shareholder and Global Creative Director, collaborating with the atelier on design and proportion. Each piece is hand-drawn, handcrafted and finished in London, with settings worked by hand and inspected before leaving the atelier.

Astrea London also offers bespoke commissions, private appointments and consultations with a gemmologist or designer, in its London salon or by video. Client services include delivery, care and repairs, and ring information.
