Solid Gold Jewelry OEM Manufacturer | 8K / 9K / 14K Carat Gold

For premium capsules and keepsake programs, we cast in solid carat gold — 8K, 9K and 14K — meaning full-body precious metal throughout, stamped and hallmarked, not a plated finish. Because our entire catalog exists as silver, brass and copper masters first, moving a proven design into solid gold is a quoting exercise, not a development project: the tooling, the setting knowledge and the QC process already exist.

What We Offer in Solid Gold

• Carat options. 8K and 9K for price-sensitive European markets; 14K for US-standard programs. We do not work in low-karat plated substitutes — solid means solid.
• Weight engineering. Our R&D team models each piece to hit a target metal weight and retail price point, using hollow-back construction or reduced gauges where the design allows without hurting durability.
• Hallmarking. Carat stamps and required marks applied per your market’s rules; tell us the destination market during quoting.
• Stone setting. CZ, pearls and precious stones set in solid gold bodies with the same 8-checkpoint QC process as our silver lines.

OEM / ODM Process

Send a sketch, CAD file or reference link. We return a costing sheet against the live gold price with a locked metal weight, produce a resin and first article for approval (sampling 7–12 days), then run bulk production in 20–35 days. Because gold pricing moves daily, quotes specify weight and labor separately so re-quotes track the market transparently instead of hiding movement in a round number.

Compliance

Solid gold programs are supported with SGS assay and composition reporting, GB 11887 conformity and nickel-release testing (EN 1811) for alloys intended to touch skin. Export documentation and material declarations are prepared per shipment.

Who This Line Suits

• Premium capsules from fashion brands extending upward from plated lines.
• Gift and graduation programs where the metal itself carries the value story.
• Retailers in 8K/9K markets (UK, Germany, Nordics) needing low-carat solid gold at wholesale scale.

MOQ and Lead Times

MOQ 30 pieces per design · Sampling 7–12 days · Bulk production 20–35 days · quoted against the live gold market · SGS / GB 11887 / EN 1811 tested.

From the Existing Catalog

Most of our sterling silver and gold plated brass designs can be quoted in solid gold — for example the Coin Relief Ring and the Apollo Coin Wheat Pendant Necklace. Ask for a solid gold quote on any style page.

Choosing the Carat: 8K, 9K or 14K

Carat choice drives hardness, color and cost at the same time. 8K and 9K alloys are harder and more scratch-resistant, which suits slim shanks, fine chains and stone-set designs that take daily wear; they also carry a lower metal cost and are the standard precious-metal claim in many European and Asian markets. 14K gives a richer yellow and a heavier feel for premium lines. We quote all three against the same design so you can see the trade-off in grams, durability and retail positioning before you commit to a collection.

Weight Engineering and Hollow Construction

Solid gold programs are won or lost on weight. We build CAD models with wall thickness and hollow sections tuned to your target gram weight, then confirm the real cast weight on the first article. Bangle bodies, pendant backs and ring shanks are the usual places to remove metal without changing how the piece reads in the hand. Every quote states the expected weight range per size so your landed cost does not drift between production runs.

Hallmarking, Assay and Chain of Custody

Precious-metal pieces carry legal marking obligations that vary by destination. We stamp the fineness mark (8K / 9K / 14K equivalents), our maker’s mark and any customer-required marks, and can supply assay certificates and material statements with each shipment. Metal is purchased through documented channels and kept segregated by customer program on the floor, so the alloy in your carton matches the alloy on your invoice.
