Industrial cluster: Panyu Jewelry and Gem-set Manufacturing Cluster

Jewelry in Guangzhou

Guangzhou's jewellery trade is anchored in Panyu District, which the district registries describe as a concentration of precious metal trading and manufacturing. The trade runs from metal sourcing through casting and stone setting to finishing - all within a few square kilometres.

Panyu's jewellery supply chain is unusual in that the same street can serve a fast-fashion order and a premium jewellery order on the same day. The metal trading houses run the upstream; the jewellery factories run the midstream; and the stone setting and finishing houses run the downstream. A buyer who walks the metal market first, then the factory, then the stone supplier is seeing three links of the same supply chain.

What we do not publish. We give no per-building or per-floor category map, no stall prices and no turnover figures. No operator here publishes floor-level trading data, tenancy changes, and a map assembled from memory would send you to the wrong lift. Confirm each building's current mix on arrival.

What to check before you order

Metal type and alloy. Ask what the metal is (gold 18K/14K, silver 925, platinum Pt950, base metals), and what the alloy composition is. The metal type and alloy affect both the price and the durability of the finished piece.

Gemstone type and setting. Ask what the gemstone is, and what the setting technique is (prong, bezel, channel). The gemstone type and setting affect both the look and the durability of the finished piece.

Compliance. Ask whether the factory holds ISO 9001 for quality management, and whether it participates in the Kimberley Process Certification Scheme for diamond sourcing compliance.

Where the mistakes happen

Substitution and mixed lots. The same-day stock pull that makes Panyu useful also means an order can be filled from whatever is on the shelf. If your build needs a single lot or a single metal batch, say so in writing.

Packaging assumptions. Bulk polybags and plain cartons are the default for industrial components. Cartons marked for your market, printed labels and rework are separate work, quoted separately and often discovered at the wrong moment.

Sampling. If you will inspect on arrival, agree the sampling plan before production starts, not after the cartons are closed. ISO 2859-1 is the procedure most inspection houses already work to.

We publish no per-building or per-floor category maps, stall prices, or turnover figures. Building tenancy changes and no operator publishes floor-level data. Treat each building's current mix as something you confirm on arrival, and treat any figure quoted to you elsewhere as a starting point for negotiation rather than a market rate.

Technical notes

• Metal types: gold (22K, 18K, 14K), silver (925 sterling), platinum (Pt950), and base metals (nickel, brass); each has different durability, color, and price.
• Gemstones: diamonds (4Cs: cut, color, clarity, carat), gemstones (ruby, sapphire, emerald), and synthetic stones; certification and treatment disclosure matter.
• Setting techniques: prong (most common), channel (flush set), bezel (wraps stone), and pave (many small stones); each offers different security and visual appeal.

Production capabilities

• Jewelry factories handle design, casting, stone setting, finishing, and quality control.
• Common processes include design (CAD), casting (investment casting), stone setting (prong, channel, bezel), and finishing (polishing, plating).
• Specialized equipment includes CAD software, casting machines, stone setting tools, and polishing machines.

Customization options

• OEM: Factory produces based on your design and material spec. MOQ is 50+ pieces per design.
• ODM: Factory provides in-house designs or modifies existing styles. MOQ is 20+ pieces per design.
• Custom development: Full design from scratch, including stone sourcing. MOQ is 100+ pieces and lead time is 60-90 days.

Common specifications

• Metal types: Gold (22K, 18K, 14K), silver (925 sterling), platinum (Pt950), base metals (nickel, brass). Metal type affects durability, color, and price.
• Gemstones: Diamonds (4Cs: cut, color, clarity, carat), gemstones (ruby, sapphire, emerald), synthetic stones. Certification and treatment disclosure matter.
• Setting techniques: Prong (most common), channel (flush set), bezel (wraps stone), pave (many small stones). Setting affects security and visual appeal.

Industry standards

• ISO 9001: Quality management system certification.
• Kimberley Process Certification Scheme: Diamond sourcing compliance.
• Fair trade / responsible sourcing certifications (if applicable).

Logistics & shipping

• Common shipping: FCL for 20+ cartons, LCL for smaller orders.
• Packaging: Each piece is boxed, then cartoned (50-100 pieces per carton). Carton size is typically 50x40x40 cm.
• Transit time: 25-35 days by sea, 5-10 days by air.

Payment terms

• Standard terms: 50% T/T deposit, 50% T/T balance before shipment.
• Alternative: Letter of Credit (L/C) at sight for large orders.
• Sample payment: 100% upfront, refunded or credited against bulk order.

Quality benchmarks

• Check metal: Proper alloy, consistent color, no cracks or flaws. Metal should be functional.
• Check stones: Proper setting, no loose stones, consistent color and clarity. Stones should be secure.
• Check finishing: Smooth polishing, proper plating, no scratches or flaws. Finishing should be compliant.

Buyer's checklist

• Confirm metal type, gemstone type, and setting technique before placing order.
• Request material sample and finished piece sample for quality verification.
• Provide clear design, material spec, and stone requirements.

Frequently asked questions

Category-level guidance only. Confirm specific MOQ, lead time, and certification with each factory before ordering.

What is the typical MOQ for jewelry?

Most factories work with 50-200 pieces per design and stone size. Some accept 10-50 pieces for existing designs. Custom design and stone sourcing usually requires 100+ pieces.

Do you offer OEM/ODM services?

Yes. Many jewelry factories provide OEM production based on your design, and some offer ODM with in-house design teams. Custom design and stone sourcing increase MOQ and lead time.

What certifications should I check?

Look for ISO 9001 for quality management, and Kimberley Process Certification Scheme for diamond sourcing. Some factories also hold fair trade or responsible sourcing certifications.

What is the lead time?

Standard production takes 20-35 days depending on design complexity. Custom design and stone sourcing adds 4-8 weeks. Large orders may require 45-60 days during peak seasons.
