Original equipment manufacturing (OEM) is how most pearl jewellery brands scale: you own the design, a specialist factory produces it. In a competitive market — Hong Kong's exports of pearls, gemstones and rough diamonds rose 10% year-on-year to HK$78.3 billion in January–August 2026[6] — access to a capable custom pearl jewelry manufacturer is a commercial advantage, not a procurement detail. This page explains the OEM process, how MOQ works, where quality is won or lost, and what to agree in writing before production starts.
Two service models dominate. OEM (original equipment manufacturing): you supply the design — sketch, CAD or reference sample — and the factory engineers and produces it to your specification. ODM (original design manufacturing): you start from the factory's existing designs and customise metals, finishes or pearl type under your brand. OEM suits brands with a distinct design identity; ODM shortens time-to-market for newer labels. Ask a prospective manufacturer which model a quote assumes — the IP and tooling implications differ.
MOQ is the smallest quantity a manufacturer will accept per production run, quoted per design or SKU, sometimes per total order. It exists for physical reasons: casting runs, mould amortisation, plating batches and pearl lots all have setup costs that only volume recovers. Practical implications for buyers:
A Concept Group's MOQ per design depends on the style and materials — typically 100 pieces per design to start; mixed-SKU terms available on request.
Agree in writing: a tech pack (dimensions, tolerances, materials, pearl grades), who owns moulds and designs, sample-approval gates before mass production, substitution rules if specified pearls are unavailable, and one named contact for the project. Miscommunication about pearl grade — not gold price — is the most common cause of OEM disputes; GIA's seven value factors[1] give you the vocabulary to prevent it.
A Concept Group Limited combines a Hong Kong wholesale base with its own factory in China, offering OEM pearl jewellery manufacturing across akoya, freshwater, Tahitian and South Sea pearls. The company is a Hong Kong Category A registered dealer (no. A-B-23-10-02147), was founded in 2015, and its family has traded pearls since 1986 — four decades of supplier relationships behind every production run. Production capacity runs to approximately 1,000–5,000 pieces per month depending on design complexity, with every piece hand-finished.
