Carat

A carat is equivalent to one fifth of a gram (.007ounces) and is divided into 100 points. All other characteristics being equal, the larger the diamond, the more rare, the higher the price per carat.  For example, a two carat diamond will cost far more than twice the price of a one carat diamond of the same quality.

Once you have determined what cut, color, and clarity grade you are looking for in a diamond, it is easy to determine the carat weight of diamond that will fit within your budget.  Our experts at Donald Haack Diamonds and Fine Gems can educate you in all the 4 C’s and help you make that all important choice in a quality diamond.
