Sampling is more efficient when the most important design decisions have already been made. The goal is not to freeze every minor preference too early. It is to prevent a sample from being produced on the basis of assumptions that could have been clarified in the brief.

1. Confirm the correct design version

Identify the approved sketch, drawing or CAD reference by date or revision number. If several images are being used, state which one controls the overall design and which ones show individual details. Remove superseded drawings from the active review pack or label them clearly as reference only.

2. Define key dimensions and proportions

List the measurements that materially affect the design. For rings, this may include ring size, band width and thickness, centre setting height and stone dimensions. For earrings, define drop length, overall width, post position and preferred scale. For pendants, include body dimensions, bail opening and chain compatibility. For bracelets, state the finished length and closure requirements.

Use units consistently. If a measurement is estimated, identify it as a target for discussion rather than a tolerance.

3. Confirm metal and gemstone descriptions

“18K gold” is more informative than “gold,” but the exact alloy color and finish may still need confirmation. “Blue sapphire” identifies a gemstone direction, but natural or laboratory-created status, treatment and any origin claim may require additional evidence.

For diamonds, clarify natural versus laboratory-grown status and any grading documentation required. For moissanite and cubic zirconia, use the correct material name. The FTC Jewelry Guides provide a useful reference for truthful descriptions of gemstones and precious metals.

4. Resolve setting and construction choices

Confirm how stones are held, how components connect and how moving parts operate. Discuss prong, bezel, channel or other setting approaches where relevant. Check whether the chosen stone dimensions and the design leave enough room for the intended construction.

Do not assume that a front view explains the underside, gallery, clasp or connection details. Add a side or back drawing when those areas matter.

5. Define finish and functional expectations

Specify polished, brushed, matte, textured or other intended surface appearance. Describe the function of clasps, hinges, posts, backs, chain connections and adjustable parts. Mention comfort, snagging, balance or weight concerns that are important to the wearer or customer.

6. Agree what the sample will and will not prove

A sample may use a proposed material or a substitute while a final component remains under confirmation. State any such limitation before the sample is evaluated. Identify who will approve it and whether the approval authorizes only another revision or the next agreed production stage.

Pre-sampling confirmation list

  • Correct drawing and reference set.
  • Design features that must remain unchanged.
  • Confirmed dimensions and size system.
  • Metal description, fineness, color and finish.
  • Gemstone identity, dimensions and origin category where known.
  • Setting, joining, closure and construction details.
  • Intended wear and functional requirements.
  • Known substitutions or unresolved items.
  • Approval person and next-step conditions.

Frequently asked questions

Should every measurement be final before sampling? Not necessarily. Critical dimensions should be defined, while unresolved values can be identified as targets. The sample should not be treated as a final specification until those values are confirmed.

Can a gemstone be substituted for a sample? Sometimes a proposed substitute can help assess proportions or construction, but it must be disclosed and cannot verify the final stone's appearance or identity. Record the difference clearly.

Who decides when a design is ready for sampling? The project owner should confirm that the brief is sufficiently clear, with technical questions reviewed by the design or manufacturing participants responsible for them.
