Diamond Rating Scale
A diamond rating scale can be a little complicated, considering most of the evaluation is done under magnification. Diamonds are rated on a magnification scale of 10 times and are based on four elements, they are: 1. Clarity 2. Cut 3. Color 4. Carat Having a little understanding of the four elements will help you to understand the cost of a diamond. Let¡¯s talk about the clarity of a diamond or in other words the way the light reflects through the diamond. The less imperfections found on the inside of a diamond, the less flawed the diamond is. All diamonds have a degree of imperfection so the ones that are less flawed are the most valuable. The cut of a diamond is the way the jeweler converts a rough diamond into a polished, shimmering diamond. This is very important to the value of the stone; if the cut is not perfect, the diamond will lose its value. This is the only part of a diamond¡¯s value that is determined by a person. The color of a diamond affects the value of a diamond. The less color a diamond has the more valuable it will be. It is very hard to see a color difference in diamonds, so to rate this element it has to be done under controlled lighting. The color of the diamond is put into a group and is rated from D to Z. The diamonds that fall into the D, E or F groups, are the ones with the less color, they are the rarest and most expensive diamonds available. A diamond that falls into the S to Z group will be of less value. The carat of a diamond is usually associated with the how big the diamond is, but this is a misconception. The carat is actually the weight of a diamond, not the size of a diamond. The more a diamond weighs the more it costs. Understanding a little about the diamond rating scale will give you an idea of how to rate a diamond¡¯s value, before you purchase it.
