Orders & minimums

Start with the right production route for your collection.

What is the minimum order for ODM jewelry?

For silver and gold vermeil jewelry, the ODM minimum is 25 pieces per design. Minimum quantities for gold jewelry are negotiable.

Share your design and planned quantity so we can confirm the right order size for your project.

Can I split one design into different plating or stone colors?

Yes. Within the applicable minimum order, you can divide a design into different plating and/or stone color options. Include your preferred combinations and quantities when requesting a quotation.

What is the minimum order for custom OEM designs?

OEM minimum quantities are quoted for each project. They depend on the design and the scope of your order.

Send us your sketches, references or CAD files, along with your preferred materials and quantities, to discuss your requirements.

How much does a mold cost?

Mold development typically costs US$80–150, depending on design complexity.

Mold development costs are waived when you order 200 pieces or more of the same design after final sample approval. Your quotation will confirm the applicable charges.

Can you manufacture jewelry for my own brand?

Yes. Our focus is manufacturing jewelry for other brands, including startups and established businesses. We develop and produce pieces based on your designs, materials and collection requirements.

Whether you have a finished design or an early concept, we can help you take the next step.

Design, samples & timelines

Know what happens between your first idea and production.

Can you create CAD models from my ideas?

Yes. Share sketches, reference images, existing CAD files or a description of your idea. Our team develops 3D CAD models using Rhino and Matrix, then shares them with you for review and approval.

Do you have an in-house design team?

Yes. Our in-house designers can develop concepts with you or collaborate with your own design team. We can work from a detailed brief or help develop an initial idea into a production-ready design.

How long does 3D modelling take?

3D modelling usually takes 3–4 days. Design complexity and revisions can affect the schedule.

You review the model before the project moves to sampling.

How long does sampling take, and do I approve the sample?

Sampling takes around 1 week. You review and approve the sample before production begins.

Use this stage to check the design and finish and discuss any adjustments with our team.

How long does production take?

Production takes around 2–3 weeks after sample approval, depending on order quantity and design complexity.

These are approximate manufacturing times. Your project quotation confirms the schedule; shipping time is separate.

Materials & quality

Understand the materials and checks behind your collection.

Which metals do you work with?

We work with 925 sterling silver, gold vermeil, and 9k, 10k, 14k and 18k gold.

Our focus is gold and silver jewelry. We do not manufacture in brass or stainless steel.

How do you check the quality of the finished jewelry?

We inspect pieces at multiple stages of production, including stone settings, surface finish and the details of the design. Finished pieces receive a final quality check before shipment.

If your collection has specific inspection requirements, share them when discussing the project.

How do you verify gold and silver purity?

Our material checks include purity assays and X-ray fluorescence (XRF) testing, alongside supplier verification and in-house checks. These help us verify metal content and monitor consistency during production.

Do you carry out factory audits?

Yes. Our audit process includes internal and third-party reviews of production quality, working conditions, workplace safety and environmental practices. Identified issues are followed up with corrective actions.

Contact us to discuss any audit or documentation requirements for your brand.

Can you support larger production orders?

Yes. Our typical production volume is 70,000–90,000 pieces per month, with capacity of up to 110,000–130,000 pieces per month.

The schedule for your collection depends on the designs, quantities and production availability. Contact us early to plan larger orders.

Delivery & confidentiality

Plan your shipment and understand how we protect your work.

Which couriers can you ship with?

We offer shipping through DHL, UPS and FedEx. The most suitable option depends on your destination, budget and delivery needs.

Share your delivery address when requesting a quotation so we can discuss the shipping options for your order.

Will my designs be kept confidential?

Yes. We can sign a mutual non-disclosure agreement (NDA) before you share confidential design details. We respect your intellectual property and protect your proprietary designs throughout the collaboration.

Learn about our confidentiality process.

Can you tell me which brands you work with?

We do not disclose client identities or confidential project details under our non-disclosure policy. Your brand receives the same protection.
