Basic Diamond Education

Acquiring knowledge of the 4 C’s is crucial before purchasing a diamond

    • Carat
    • Cut
    • Clarity
    • Color

By understanding each diamond characteristic and knowing which questions to ask when purchasing a diamond, you are much more empowered when it comes time to make your diamond investment.


Carat is the weight of the diamond. Stones of high quality can be found in a variety of sizes and price ranges. However this does not always determine how large the stone actually looks. When determining what carat weight you want in a diamond, you should consider two other things. 1. The distance across the top of the stone, as this is what you will see once the stone is set.  2. The cut grade, which determines how much light the stone picks up.

Cut is arguably the most important of the 4 C’s. Often mistaken as the diamond’s shape, cut can get overlooked. A diamond’s cut has the most influence on the sparkle and beauty of the stone. Cut measures the light picked up by the diamond and when it is cut to proper proportions light is reflected out the top of the stone. Shallow or deeply cut stones send light out the side or the bottom resulting in a dull appearance.

Clarity is the measure of a diamond’s internal flaws and impurities. A diamond that is virtually free of inclusions (flaws) is of the highest quality, these stones have nothing to interfere with the passage of light through the stone. To determine clarity a 10x magnification glass is used by a trained gemologist. Small inclusions neither mar its beauty or endanger its durability.

Color is graded on a scale that varies from totally colorless to yellow. The scale starts with D, which is deemed colorless and goes all the way to Z. The further down the scale, the more yellow cast the stone will have.  Most jewelers stay in the Colorless (D-F) or Near Colorless (G-J) range.
