Learn About the 4 C’s of Diamonds

ICYMI, just a few weeks ago, we announced our partnership with jewelry retailer REEDS Jewelers, introducing Kleinfeld Fine Jewelry. Inspired by our gorgeous selection of wedding dresses, named after New York City streets and expertly crafted by family-owned REEDS Jewelers, we couldn’t be more excited about these stunning engagement rings and wedding bands (and we know you will be too)! While you may be ooo-ing and ahh-ing over the new styles, take a few minutes to educate yourself on the characteristics that make up a beautiful diamond—learn more about the 4 C’s, below.

Carat Weight

The carat refers to the weight of the diamond, and like the cut, is a very important deciding factor in choosing a diamond. The larger the carat weight, the more expensive the diamond. Keep in mind that while two stones may be the same carat weight, one may appear larger or smaller due to its cut, explained below.


The cut describes how the diamond has been shaped to reflect light in the most desirable way. Because a diamond is known to shimmer and catch light, cut is very important. A diamond can be rated poorly if it’s cut too deep or too shallow, and is rated from poor to excellent.


The clarity describes how many and how large (or how few and how small) inclusions (marks) there are on the surface and internally of a diamond.  Diamonds with the smallest and fewest inclusions have the highest clarity grade. Clarity is measured on a scale from I1-13 to FL, which means flawless. Typically, inclusions under most grades are not visible to the naked eye, but are more likely visible from I1 and beyond. Like color, trading down in clarity can allow someone with a specific budget to purchase a diamond with a larger carat weight or better cut.


The color of a diamond describes the color based on a D-Z scale, from colorless to yellow.  Because a diamond’s value is based on how well it reflects light, a clear (or colorless) diamond is the most desirable. With that, diamonds rated J or above are colorless to the naked eye. In fact, trading down in color can allow someone with a specific budget to purchase a diamond with a larger carat weight or better cut. Depending on your personal taste and goals, the color rating of a diamond may or may not be as important to you.
