Artist Wallace Chan makes tiny pictures inside precious stones like diamonds, sapphires and emeralds.

Wallace taught himself the techniques using special lasers and traditional jewellery tools.

His latest work is the face of a Greek goddess burned into the middle of a purple sapphire.

His jewellery is sold around the world, and is very popular with royalty and Hollywood stars.
