"So you are looking to buy a diamond or maybe you already have a diamond and you are wanting to know how many carats it is. The following diamond carat size chart will give you an idea as to the approximate carat weight of your diamond.http://www.ajediam.com/Sizes-of-Diamonds.htmlKeep in mind that carat is actually the measurment of the weight and not the size of a diamond, so it is possible for
. one diamond that looks bigger to actually have a smaller carat weight than a diamond of a smaller size. Use this chart for an estimate only.Also consider this, when gauging the value of a diamond, remember the 4 C's. They are Carat, Cut, Clarity, and Color. That is to say, sometimes it is preferable to have a smaller weight diamond that is more brilliant than to have a larger diamond with a less desirable cut, and color or one that has flaws.And remember, diamonds are a girl's best friend!"
