Creating a Cartier animal jewellery piece: A step-by-step process Step 1 All high jewellery begins with a detailed sketch. In the case of an animal motif, the creator would have studied the animals in pictures and at the zoo. Step 2 The animal is created in a three-dimensional green wax sculpture. It will be cast in precious metal. Step 3 The jeweller completes the openwork on the metal, fashioning a special piece with the artisan's personality. Step 4 In most cases, the creation is centred around a specific stone, and the finished product is the result of a team effort between the master craftsmen and designers.
