The Maison
A House built on light
Astrea London was founded on a single conviction: that the finest jewellery should be made without compromise, in materials of absolute purity. Every piece is drawn in London, set by hand, and finished to the standards of high jewellery. Our diamonds are grown rather than mined, which allows us to select for clarity and character without limit.
Collections

A diamond is only the beginning.True luxury is the detail no one else sees.
Featured Pieces
Selected by the atelier

Craftsmanship
Set by hand,considered twice
Each setting is worked under the loupe by a single hand, from wax model to final polish. Stones are matched by eye as well as by certificate, because two diamonds of identical grade rarely wear the same. Nothing leaves the atelier until it has been examined a second time, by someone who did not make it.
