In each setting range, you may specify an upper or lower limit, or both. Carat weight and Depth are entered with optional decimal point, tenth, and hundredth. All other numbers are whole numbers(no decimal). No fractions(e.g. 1/4) are allowed. In the Price range, the dollar sign and comma are optional. All prices are rounded to the dollar. When selecting a Depth range, remember that after setting an upper limit of 60, for instance, the range would not include 60.1 or above.
