Astrea London at a glance
Astrea London is a modern jewellery maison creating lab-grown diamond couture and bespoke pieces — drawn in London and Paris, set by hand, and certified stone by stone by IGI and GIA.
The maison was founded on a single conviction: that the finest jewellery should be made without compromise, in materials of absolute purity. Its diamonds are grown rather than mined, its gold is certified 18k and hallmarked, and nothing leaves the atelier until it has been examined a second time, by someone who did not make it. Sarah Jessica Parker, shareholder and Global Creative Director, works with the atelier on shape and proportion across the collections.

Lab-grown diamonds
Six facts for your piece
Diamond, by every measure
A grown diamond is chemically, optically and physically diamond — the same crystal, the same fire, the same hardness 10 on the Mohs scale.
Certified like any fine stone
Every stone is graded independently by IGI or GIA — the same institutes, the same scales — and each report number can be verified with the issuing laboratory.
Grown, not mined
Our diamonds are grown in advanced reactors that recreate the conditions of the earth's mantle, with a fraction of the land and water impact of mining.
Traceable from seed to setting
Each stone can be followed from its seed through cutting to the finished piece — a continuous provenance that mining cannot offer.
A new luxury equation
A grown diamond of identical grade costs a fraction of its mined equivalent — allowing larger, rarer stones within the same budget.
Hand-finished, hallmarked
Every piece is set under the loupe by hand, in certified 18k gold — hallmarked and independently verified for purity.
The founder
A word from Nathalie Morrison
“Astrea was not created to erase the extraordinary history of the diamond. We created Astrea to honour that history by imagining what comes next.”
Nathalie Morrison founded Astrea London in December 2023 after a career in finance and entrepreneurship — and a childhood spent among the vines of Saint-Émilion, where she learned that what you create today is never only for today.
