Item categories in the valuation wizard

The Item Category you pick on the wizard's Item details step decides which steps follow. It doesn't change the certificate design.

Jewellery

Adds a Jewellery Details step: jewellery type, metal, purity and weight, hallmarks, the main stone and any secondary stones, setting, chain and clasp, ring size, engraving and measurements. Five steps in total.

Watch

Adds a Watch Details step: brand, model, reference and serial numbers, year, case, crystal, dial, strap or bracelet, movement, complications, box, papers, warranty card and service history. Five steps in total.

Loose Gemstone, Antique / Vintage, Collectible and General Item

These go straight from Item details to Valuation — four steps in total. Describe the item in the Description and Condition Notes.

For structured grading of a single stone (shape, carat, colour, clarity and so on), choose Jewellery and set the jewellery type to Loose Stone; the Jewellery Details step then gives you the stone fields.

Certificate design

Every certificate on the account uses the one design chosen in Settings > Branding, whatever the category. The certificate headline follows the valuation's basis of value — see Purpose and basis of value.
