For a rhodium-plated style, identify the base metal and the intended appearance separately from the deposited coating. Do not infer thickness, composition or service life from a photograph.
- Base metal
- State the metal, gold fineness where applicable, and any underlayer to be reviewed.
- Coating & color
- Record the coating material and an approved color reference; confirm compatibility with the design.
- Thickness
- State the required coating thickness in micrometers (μm), whether it is a target or minimum, and the agreed measurement method.
- Verification
- Agree the measurement method, locations and acceptance criteria: agreed for the finish specification and order.
- Quotation wording
- Keep the base metal, coating, thickness and finish as separate entries. Do not use “rhodium finish” as a substitute for these details.
Plating values and verification arrangements are agreed for each project. No standard thickness or wear guarantee is implied here.
