GUILLOCHÉ / ENGINE-TURNING
A technique of engraving close-together, narrow, parallel lines on metal. These lines can be intertwining, undulating, circular or another shape. The finished motif creates a subtle relief and catches the light. Following Russian jeweler Peter Carl Fabergé, Cartier designed numerous objects (desk sets, powder compacts, cigarette cases and card holders) with an enameled motif against a guilloché background to create a rippled or moiré effect.Cartier also made extensive use of guilloché effect alone, without enamel, to decorate pens or watch dials for example.
