Export workflow

Built for repeat B2B shipments

For overseas buyers, the operational details matter: packing, certificate files, inspection notes, invoice references, and reorder history all need to be clean.

  • Selected stones and parcels packed by specification.
  • Shipment file with packing list, certificate file, and buyer reference.
  • Packing options for dealers, brands, and jewelry production teams.
  • Order history kept for faster reorder matching.

Sourcing

Match demand to available production and wholesale inventory across loose, certified, HPHT, CVD, melee, and bulk programs.

Shipment

Prepare export packing, order files, certificate references, and delivery follow-up for repeat buyers.

Proof to add

Factory proof should be real and buyer-verifiable

The site should not invent machines, certifications, customer names, or capacity claims. Use this section as a controlled placeholder for real media and documents when they are available.

TODO: factory media
Replace this note with approved production-line, sorting, packing, or office photos owned by the supplier.
TODO: capacity evidence
Add real capacity, team, equipment, or weekly sourcing data only after the business confirms the numbers.
TODO: buyer proof
Add buyer-approved case examples only when names, photos, and results are cleared for public use.
