Proper orientation of the rough material is essential to insure the maximum brilliance in a gemstone. Shadows will occur because of light loss if the stone is cut to retain carat weight. The way to judge cutting is the amount of brilliance (life) the gemstone returns to the eye. Well cut gemstones will "talk" to you with their brilliance.
A poorly cut gemstone is easily noticed. A large washed out center, or "window", in a gemstone is a result of incorrect proportions. This occurs generally when the stone is cut too shallow. Gemstones cut too deep will wash out around the edge of the stone. Flat or overly deep gemstones may prove a problem in setting also.
