How to start a fine jewellery brand with a manufacturer

By Osia International · Last reviewed 12 November 2026

Osia is wholesale and trade only. It does not sell to the public. The steps below are for new labels, boutiques and retailers who want to work with a manufacturer.

Three ways to launch (ODM, private label, OEM)

There are three routes. They are described in full on ODM vs OEM; this is only a short start-here guide.

ODM (Osia catalogue designs). You choose designs from Osia's catalogue and can adapt the metal, size or stones, then add your brand stamping. Catalogue designs are non-exclusive and available to any trade account. For many new labels, this is the simplest place to start.

Private label (to your brief). Osia's design team develops a line around your brief, references or target price point. Designs developed to your brief are exclusive to you, and Osia releases the CAD and JCD files to you. This is the route if you want an exclusive line but do not already have finished designs. See private label jewellery manufacturing.

OEM (your own design). You send a CAD file or a sketch, and Osia manages production to that design. Your designs are exclusive to you, and Osia releases the CAD and JCD files to you.

You do not need your own designer if you start with ODM or private label. If you already have a file, use OEM. The production model is the same on every route: Osia designs, specifies and manages production end-to-end. Casting is done in partner production factories. Stone setting is done either locally in Hong Kong or at partner workshops and factories, depending on the job. Osia does not own the factory. A fuller picture of materials and process is on manufacturing, and a short company background is on About Osia.

A realistic sequence

1. 1

   Apply for a trade account at signup.php. Applications are reviewed by hand, usually within 7 days. After approval, you can see live inventory and wholesale pricing in the trade portal. Those prices are not published on this page.

2. 2

   Choose a route and send a brief. That can be catalogue picks (ODM), a brief, references or a target price point (private label), or a CAD file or sketch (OEM). You can also send a trade enquiry to web@osiaintl.com, or use the contact page. Australian retailers can start through the Sydney office — see wholesale jewellery for Australia.

3. 3

   Approve the design on 3D CAD renders. There is no physical sample or prototype stage. Production does not start from a wax model or a sample piece.

4. 4

   Quote, then a 50% deposit for made-to-order work. Once you accept the quote, a 50% deposit starts made-to-order production, and the balance is due before shipment. In-stock catalogue orders are paid in full up front. Deposit, cancellation and refund terms are in our Trade Policies.

5. 5

   Production and two-stage quality control. Every piece is checked twice: once at factory level, and again by Osia before dispatch, including diamond testing in Osia's in-house quality control.

6. 6

   Delivery. Orders ship by DHL Express or FedEx, insured for the full declared value, with signature required on delivery. Lead times and shipping terms are on shipping. Trade account terms are on policies.

Time and minimum order

These are the confirmed lead times from the shipping page:

• In-stock catalogue: typically 3–7 business days to ship, from payment.
• Fully bespoke (from CAD): typically 25–45 business days, design-dependent, from deposit received. Complex stone-setting, fancy-shape diamonds and platinum sit at the upper end of the range.
• Repeat private-label orders: typically 3–4 weeks for a simple piece, or 4–5 weeks for a more complicated piece (more diamond setting or stone-sourcing complexity).

There is no minimum order on custom and private-label jewellery work.

That "no minimum" line applies to jewellery. It does not apply automatically to loose lab-grown diamonds. For loose lab-grown stones, the minimum order is on request — ask us, or see wholesale lab-grown diamonds. This page does not list lab-grown grades, size bands, stock counts or prices.

What you will need to decide

Metals. Osia works in 9K–22K white, yellow and rose gold, 925 sterling to 960 Argentium silver, and Pt900 to Pt950 platinum.

Stones. Most commissions use Osia's own certified inventory; client-supplied stones can also be set. Published ranges for loose natural diamonds are 0.30ct to 10ct, IF–I1 clarity, D–O colour, independently certified (GIA, IGI or HRD). For current lab-grown availability, ask us — grades and prices are not published on public pages.

Brand stamping and exclusivity. Logo and brand stamping are part of every private-label specification, including on catalogue (ODM) designs. ODM catalogue designs stay non-exclusive. Private-label and OEM designs are exclusive to you. NDA is standard.

Packaging. Branded packaging is not a standard offer. It can be arranged on request and is quoted with the order.

Costs, without publishing prices

Osia does not publish wholesale prices, start-up budgets, tooling fees or "from" prices on public pages. A quote is driven by the metal, the stones, the complexity of the work, and the lead time. Once your trade account is approved, wholesale pricing is visible in the trade portal, and any custom work is quoted to you directly. The final figure is agreed before production starts.
