3. Stone specification

Colour, clarity and calibration tolerance for each stone.

5. Quantity & forecast

Pieces per style, number of styles, and a 12-month forecast.

2. Metal specification

4. Finish & plating

Polish finish; plating in rhodium, yellow or rose gold, or black ruthenium.

6. Destination market

Target market, so packing, hallmarking and documentation match.

7. Target landed cost

Ownership and branding

Private label ownership

Finished jewellery under your own brand name. Your designs and tooling remain exclusively yours. Maker's mark, hang tags, boxes and barcodes to your specification, with full documentation for your inventory and wholesale distribution.
