Laser engraving, or “etching”, is a non-contact technique that removes the surface material of an object to create a permanent image. In contrast to traditional engraving, laser engraving is appropriate for not only soft metals such as silver or gold, but also for harder surfaces such as rings, bracelets, earrings and watches. Furthermore, laser engraving can be applied to both flat and curved surfaces due to its intensive precision. Most importantly, this procedure leaves the engraved product damage-free.
