Just as a dollar is divided into 100 pennies, a carat is divided into 100 points. For example, a 50-point diamond weighs 0.50 carats. But two diamonds of equal weight can have very different values depending on the Four C’s: clarity, color and cut. The cut, color, clarity and carat weight are what give a diamond it’s beauty, it’s brilliance and ultimately it’s value.
Don’t confuse carat with karat, as in “18K gold” which refers to gold purity.Is the shape of a diamond a value factor? Yes, put simply, if all grading factors are equal, round diamonds cost about 15% to 30% more than other shapes.
Learning about the 4 C’s of diamonds is important. A quick hands on presentation after reading or watching the GIA video tutorials will facilitate questions and help you become an informed decision maker. GIA, creator of the diamond grading system, is the accepted worldwide authority on diamonds.
