What to Expect
Placing an Order
Every Ouie piece begins its life with intent. We do not hold inventory and each order is made specifically for you.
You can place your order directly through our website, or, for more significant purchases, request a one-on-one appointment with our concierge. These private consultations are available in person or online, and allow for deeper discussion around bespoke considerations or specific requests.
The Manufacturing Process
Once your order is confirmed, your piece enters production. It will be built by hand in one of our trusted specialist ateliers, a process that balances traditional techniques with precision-led innovation including CNC machining. On average, production takes up to seven weeks from the point of order, though timelines may vary slightly depending on the complexity of the piece or seasonality.
Every piece is individually quality checked by our internal team before it is sent for hallmarking. Ouie pieces carry a full UK hallmark, certified by the London Assay Office — a final step that ensures authenticity and material integrity. Hallmarking typically takes one additional week.
Packaing and Delivery
Packaging is tailored to the piece:
- Orders under £3,000 are delivered in a drawstring dust bag made from vintage cotton-check fabrics, individually sourced in limited quantities and never repeated.
- Orders over £3,000 arrive in our signature machine-milled aluminium hard case, accompanied by the cotton dust bag. These cases are also available separately for gifting or storage.
Once complete, your order is shipped fully insured via DHL Express. Worldwide delivery typically takes 1–3 working days, depending on your location. All shipments are tracked, signed for, and discreetly packaged.
Aftercare
Your order includes a certificate of authenticity and is covered by a lifetime manufacturing guarantee. We also offer one complimentary service within the first year of purchase. Further services are available on request.

Product Care
Jewellery Care
Each Ouie creation is precious and deserves the highest level of care. With our array of services, you can maintain the brilliance and longevity of your Ouie jewellery, including cleaning and polishing, for a fee. Please contact our concierge with any questions or to arrange a service.
Sterling Silver
To preserve the polish of your sterling silver jewellery, avoid exposure to household cleaning products, bleach and other strong chemicals. We recommend that you store your silver jewellery in its cotton pouch. To clean, apply a small amount of silver polish to a soft cloth, then gently rub the silver with the cloth several times. Rinse the silver thoroughly in warm water and blot dry and shine your silver with a polishing cloth or mitts to remove tarnish and restore shine.
Gold and Platinum
To preserve the polish of your gold and platinum jewellery, avoid exposure to household cleaning products and bleach. We recommend that you store your jewellery in its cotton pouch for safekeeping.
1. Place your gold or platinum jewellery into the cleaner solution.
2. After two minutes, gently remove your jewellery from the solution.
3. Gently clean behind the settings and in between crevices with a soft bristle brush to remove any debris.
4. Rinse, blot dry and shine your gold or platinum jewellery with a polishing cloth.
Gemstones and Pearls
We recommend that you avoid exposing diamond, gemstone and pearl jewellery to variable temperatures, cosmetics and ultrasonic cleaning.
1. Place your gemstone jewellery into some jewellery cleaner solution.
2. After two minutes, gently remove your jewellery from the solution.
3. Gently clean behind the settings and in between crevices with a soft bristle brush to remove any debris.
4. Rinse the jewellery and dry with a polishing cloth.
NOTE: Delicate gemstones can be cleaned with a soft brush and a mild soap and water solution.
If worn often, pearls should be professionally cleaned once a year.
Size Guide
Ring Sizing
Our jewellery is sized using British alphabetical sizing. If you need to convert a European or American size to British sizing please see chart below.
If you have a ring that already fits you, you can easily calculate the ring size by measuring the diameter. Use a ruler or measuring tape and measure the internal diameter of the ring and compare it to the chart.

Necklace Sizing
If you have a necklace at the desired length, measure it from one clasp to the other when laid straight on a flat surface. If you don't have a necklace, use a measuring tape or string to determine your desired length.
Using a tape measure, place it around your neck and meet the ends where you would like the pendant to fall on your chest. Take note of the length.
Alternatively, you can use a piece of string. Place the string around your neck and meet the ends where you would like the pendant to fall on your chest. Then, measure the length of the string using a ruler or tape measure to determine your necklace size.
Bracelet Sizing
If you have a bracelet at the desired length, measure it from one clasp to the other when laid straight on a flat surface. If you don't have a bracelet, use a measuring tape or string to determine your desired length.
