You don't have to go broke buying the highest-grade diamonds. This bling is rated on cut, carat, color and clarity.While the first two are a matter of preference, color is graded alphabetically from D (colorless) to Z (yellow), and clarity follows a scale of 11, starting with FL for "flawless."
You can drop to an H in color and SI2 in clarity - the eighth category - and the flaws will be unnoticeable to the naked eye, says Helena Krodel of the Jewelry Information Center. And you'll save 75 percent off top quality.
