In jewelry, creation is the result of a team effort, for which the design is the first step. The gouaché is a technically detailed rendering which will guide all the different « hands » who will participate in the creation of the jewel. The mockup maker, the jewelers, the gemologists, the polishers, the setters: all will refer back to it during every single stage. The gouaché prefigures the jewel, both in volume and in color. In this course you will discover how the designer must perfectly express the association of color with light. From cabochon shape to faceted cuts, you will apply the techniques for gouaché which show the liveliness of the real stones.
