Answer:
Hand etching is created by a highly skilled artist. The etching artist makes a series of tiny impressions using diamond-tipped tools, directly on the granite or other monument materials. On the other hand, laser etching is formed using a laser engraving machine. It is done directly on the surface without a stencil. Both hand etching and laser etching provide the maximum amount of clarity of an image. The impressions can last for a life time.
