Gouache, the art of painting in opaque watercolour, has a particularly special place within the jewellery industry. It has been employed for centuries by jewellery designers and showcases a point where the merging of traditional artistry and fine jewellery design begins. Also known as ‘rendering,’ this art form reflects the artistic vision of the designer and serves as a guideline for the craftsmen who physically create the jewels. Haute Joaillerie is one of the few vanguards of this handmade practice.
