Some things should be discovered privately
Our Diamonds
Our stones are grown in advanced reactors that recreate the pressure and temperature conditions of the earth's mantle. They are chemically, optically and physically diamond, cut and polished to the same standards as any fine stone.
Every centre stone above 0.30ct is independently graded and arrives with its certificate. Smaller accent stones are matched in house for colour and clarity, then verified before setting.
18ct yellow, white and rose gold, and platinum 950. All alloys are responsibly sourced and hallmarked.
Orders & Delivery
Within 48 hours of your order, a member of our team will contact you to confirm it and whether your piece is in stock or needs to be specially made. Please allow up to four weeks for delivery, depending on availability and destination; we confirm an estimated date and keep you informed. Bespoke commissions follow the timeframe agreed with you.
Insured, signature-required delivery worldwide, presented in Astrea packaging with its certification. A member of the client team confirms the delivery window with you personally. Risk passes only when the piece is physically delivered to you or to a person you authorised to receive it; checkout states whether duties, customs charges and taxes are included and whether you will be the importer of record.
Yes. Collection can be arranged at any of our salons, and we are happy to present your piece privately with a gemmologist present.
Sizing, Care & Repairs
The first resize within one month of purchase is complimentary on most settings. Eternity and full-pavé designs are generally remade rather than resized; we will explain the options before any work begins.
Remove rings and bracelets before exercise, gardening, housework or manual activity, and remove necklaces before sleeping. Let perfume, moisturiser and hairspray dry before putting jewellery on. Keep pieces away from showers, swimming pools, hot tubs, chemicals, excessive heat, humidity and direct sunlight, and store each one separately in its Astrea pouch or box. After wearing, wipe gently with a clean cloth. For occasional cleaning use warm water, mild soap and a soft brush; do not use a domestic ultrasonic cleaner.
Yes. We recommend an annual inspection and offer a complimentary clean and inspection, allowing our specialists to check the settings and identify anything requiring attention early.
We do. Send us a photograph and a note and the atelier will assess the work, quote it, and return the piece cleaned and checked.
Returns & Bespoke
Every piece is inspected before dispatch. If it arrives faulty, damaged or not as described, email enquiries@astrealondon.com with your order number and photographs, ideally within 48 hours (this never limits your legal rights). We assess each case and provide the remedy required by applicable consumer law, which may include repair, replacement, a price reduction or refund. Accidental damage, misuse, normal wear and tear and unauthorised work are not treated as manufacturing faults.
You may request a voluntary return of an eligible unworn online purchase within 14 days of receipt. It must come back with its original box, grading report and accompanying materials by an insured, trackable service. Bespoke and personalised creations are excluded only from change-of-mind returns. These conditions never limit mandatory remedies for a defective, damaged, incorrect, misdescribed or non-conforming piece; for an accepted statutory claim, Astrea London bears the reasonable collection, return delivery and insurance costs.
You begin with our four-step atelier, or send us your inspiration. A designer works with you through sketches and stone selection, and we confirm the design and diamonds in writing before accepting the commission. Payment is normally 50% to begin and 50% before dispatch. If you cancel after approval, we may retain only reasonable documented work and non-recoverable costs, refunding the balance; no deduction applies where we fail to supply the agreed creation.
