A layout in jewelry is used to describe either the potential placement of diamonds, gemstones or pearls in a necklace or bracelet design- the gemstones are "laid out" on a form or piece of paper so that the designer can make alterations to the design before mounting them into place permanently. In diamond cutting, the term layout describes how a diamond cutter views or lays out his plan for cutting the rough diamond into various shapes.
