How a gemstone looks is all-important. People buy a gem so that it will look good, both to themselves and to others. That's where good cutting comes in. Many gemstones only sparkle around the outside with a kind of dead spot in the middle. this is known as a "windowed" or "fish eye" gemstone. When the bottom facets are cut at too shallow an angle, the light passes through without being reflected. This results in a stone with a ring of brightness around the outside and a lighter colored "window" in the center. (See photo.)
With a little practice, a "windowed" or "fish eye" gemstone is easy to recognize. Notice in picture that you can see right through and even read through the gem on the left with poor cutting. This is a good test to apply to any gemstone before you buy. The gemstone on the right was faceted using the correct angles on a modern machine.
Poor cutting belongs to a bygone era when customers were not educated or picky enouth to care about the quality of their gem. A simple "colored stone" becomes a real GEM with good cutting.
