Factory trust proof

VELLITH production workflow

Before quotation, buyers can confirm customization scope, production control points, inspection requirements, and export packing details with the factory team.

01. Requirement Confirmation

Confirm target market, style reference, material, stone size, quantity, budget range, and delivery country.

02. CAD & Sample Review

Prepare CAD or sample direction, check proportion, stone layout, wearing comfort, and logo position before production.

03. Stone Matching

Match stones by size, color, clarity, and cut consistency so repeated orders stay visually stable.

04. Production & Setting

Casting, polishing, setting, plating, and finishing are managed through a factory production checklist.

05. Final QC

Inspect stone security, surface finish, size, weight, plating, engraving, and packing before shipment.

06. Packing & Export

Use protective export packing, buyer label options, shipping photos, and document support for delivery.

Quality assurance

Inspection points before shipment

For B2B jewelry orders, the key risk is not only whether one sample looks good, but whether bulk production stays consistent. This section gives buyers a clear factory control story and turns the page into a stronger inquiry tool.

  • Stone tightness and setting symmetry check
  • Metal stamp, ring size, bracelet length, and product weight verification
  • Surface polishing, plating color, solder point, and scratch inspection
  • Sample approval record and repeat-order consistency control
  • Optional third-party stone certificate or product inspection document
  • Packing photo confirmation before dispatch for bulk orders

For wholesale buyers

Built for private-label and repeat-order programs

VELLITH supports ready-stock inquiries, custom jewelry development, and collection-based production for buyers who need repeatable quality, private-label presentation, and reliable export communication.

Can I change the metal, diamond size, or packaging?

Yes. Send the target material, stone specification, quantity, and brand packaging requirement. The factory will quote based on your exact configuration.

Can you make the same style for my private-label collection?

We can create a similar production direction based on your reference, then adjust details, logo, proportions, and packaging so the finished product belongs to your brand program.

What should I send to get an accurate quotation?

Please send product photo or CAD, metal type, stone size and grade, quantity, certificate requirement, packaging request, and delivery country.

Do you support sample first and then bulk production?

Yes. For new buyers or new designs, sample confirmation is recommended before repeat production or seasonal collection orders.
