Wallace Chan is a Hong Kong-based jeweler known for his imaginative jewelry designs, groundbreaking gem sculpting techniques and the spectacular prices his creations bring.
In 1987, he devised a method of carving designs within a gemstone. The technique uses cameos and intaglios to create a lifelike image. That image is then reflected within the gem to create a three-dimensional effect. A modified dentist's drill is used to make small detailed changes on the stone.
