GLOBAL CREATIVE DIRECTOR
Sarah Jessica Parker
Sarah Jessica Parker is a shareholder in Astrea London and its Global Creative Director. She works with the atelier on shape and proportion — the length of a drop, the set of a stone against the collarbone — and on the pieces she would wear herself. Her first collection with the maison was drawn for daily wear and photographed on the Croisette in the same season.
Jewellery has always been deeply personal to me
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 hand-drawn, handcrafted, 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
Eight chapters of the Maison
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.
