A product specification sheet turns a design into a structured record that can be quoted, sampled, reviewed and maintained. It is useful for one custom item and essential when a brand plans to manage several styles or repeat orders.
1. Identify the product and revision
Include product title, internal reference or SKU if confirmed, product category, collection and drawing revision. Add a date and identify the person responsible for approving changes. Do not use a planning number as a public SKU unless it has been formally assigned.
2. Record overall dimensions
List the dimensions that matter to the piece, using consistent units. Depending on the product, this may include ring size, band width and thickness, pendant length and width, chain length, earring drop, bracelet length, clasp dimensions and stone setting height.
For components with multiple views, attach dimensioned drawings or CAD references. Distinguish nominal dimensions from acceptable tolerances and from early estimates.
3. Specify metals
Name the metal and fineness, color, finish and plating where applicable. State which components use each material. If an alloy restriction is important, request the relevant material documentation. A stamp or color alone does not identify the complete composition.
4. Specify gemstones
For each stone, record material name, natural or laboratory origin category, shape, dimensions, carat weight if available, color range, treatment status and report details where required. If stone matching is important, define the acceptable range and how variations will be assessed.
Do not use the same field for diamond, moissanite and cubic zirconia. They are different materials and should be named clearly.
5. Document construction and function
Describe settings, joins, posts, clasps, hinges, bails, chain connections and moving components. Include any fit, comfort, security or wearability requirements. If the design depends on a specific connection or adjustment mechanism, show it in a drawing.
6. Record finish, customization and quality criteria
Describe polished, brushed, satin, matte or textured finishes and identify the components to which they apply. List permitted customization options and any features that must not change.
Quality criteria should be specific enough to inspect. Instead of “good finish,” identify the expected surface appearance, visible symmetry, closure function or setting condition.
7. Add packaging, compliance and documentation
Identify the intended destination market, required labels or precious-metal marks, reports, product instructions and packaging needs. The requirements depend on the product and market, so confirm them rather than copying a generic template.

Frequently asked questions
Should every product have its own specification sheet? Yes. Even related products may differ in size, setting, material or closure. Shared collection rules can be recorded separately, but item-specific data should remain clear.
Can a specification sheet include estimates? Yes, if they are marked as provisional and are not mistaken for approved requirements.
When should the sheet be updated? Whenever a design, material, dimension or approved construction detail changes. The revision record should identify what changed and who approved it.
