The 4C’s of a Diamond

What You Should Know Before You Buy A Diamond

You wouldn’t buy a car or a house without doing some research first, that’s why we’ve laid out some helpful information to assist you in making the right choice when it comes to your diamond purchase. After all, a diamond may not cost as much as your home or car, but it will be treasured long after the home is sold and the car is replaced.  The 4C’s of a Diamond will give you the confidence your need to make the right decision on your diamond purchase.

Bigger is not always better when it comes to diamonds because many factors affect the stone’s appearance and value. Four primary factors; cut, carat weight, color and clarity, called the “4 C’s,” are the most common ways of determining a diamond’s value. Although a 20-carat diamond may sound fantastic, the cut, color and clarity are the true tests of its value.



The “Brilliance” in a diamond is one of the most admired qualities. The more fire it has, the more life it has.
This does not happen accidentally. It takes a master craftsman, cutting 58 Facets along established Ideal Proportions to obtain a perfectly finished diamond. A small change in the angle of the 58 facets will reduce the brilliance dramatically.
“Life” and “Brilliance” are created by light rays bouncing and reflecting on, in and out the facets of the diamond. The angles of reflection are all important, as shown.

If your preference is other than “Brilliant” cut (round) diamond, Skatell’s can get the shape to suit your fancy.
Our selection includes exceptionally well proportioned “Fancy” cuts such as Marquise, Oval and Pear as well as more exotic cuts such as Emerald cut, Heart, and Princess cut diamonds.




Most people think of diamonds as being colorless. While colorless diamonds are the most routinely sought after, these sparkling gems can also occur in a wide variety of glorious natural colors.

These rare exceptions, called “Fancy” colored diamonds, can be found in any color of the rainbow. The magnificent 44 1/2 carat Hope Diamond, for instance, is blue and the 128 carat Tiffany Diamond is yellow.

“Clarity” describes the various internal flaws in a diamond. These are the “fingerprints” of a diamond and no two are alike.

The number and the type of flaws, and whether or not they are visible to the unaided eye are factors in determining the price you pay for your diamond.
Keep in mind that minor flaws, invisible to the unaided eye, do not detract from the beauty of a diamond but do affect the price.

While Karat pertains to the pure gold content of the mounting of your ring, CARAT refers to the size of your diamond and is a measure of weight. A carat is divided into 100 points.

Carat weight alone does not determine the value of a diamond. For instance, it is very possible for a smaller diamond to be worth much more than a larger one. The other three C’s must be considered when assigning value to a diamond.
