When buying diamonds, it is important to consider four key factors: clarity, carat, color, cut. Dubbed the four Cs by diamond experts, the higher quality the diamond, the more money it is worth based on this scale.


Clarity is the presence or absence of inclusions or flaws in the stone. Our experts will rank your diamond using industry standards in order to ensure that you are paid top price for your jewelry. Clarity grade is determined on a scale of decreasing clarity from the highest clarity (Flawless or FL) to the lowest clarity (Included 3, or I3). The modern clarity scale was invented in the 1950s, by a former president of GIA, Richard T. Liddicoat, Jr. With minor modifications, it has been the universal standard ever since, using verbal descriptors most are now familiar with: Flawless, Internally Flawless, VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, and I3.


Carat is the unit of measurement for the physical weight of diamonds. One carat equals 0.200 grams or 1/5 gram and is subdivided into 100 points. Large diamonds are rarer than smaller ones, and as the carat weight increases, the value increases as well. However, the increase in value is not proportionate to the size increase.


Perfectly colorless diamonds are considered the highest quality with the highest value, and brown or yellow being the lowest quality.

Colorless: This is the highest grade possible, and diamonds without color are very rare. Therefore, they cost more on the market.
Near Colorless: These diamonds have very little color. Interestingly, when mounted in jewelry, they will appear colorless.

Faint Color: If a diamond in these grades weigh less than approximately 0.50 carat, it will appear colorless when mounted. In a larger diamond, a little color may be discerned. Keep this tip in mind when shopping; you could save money and walk away with a diamond that looks like a higher Color Grade.

Very Light Color: A diamond in these grades will show some discernable color. The larger the diamond, the more noticeable the color.

Light Color: The color is seen with increasing ease as the grade goes from 7.5 to 10.


The cut of a diamond refers to how well the facets interact with light, the proportions and the overall finish of the diamond. It is not to be confused with the shape, (like emerald or round,) or facet arrangement, (like brilliant, or step cut), but is instead a reference to the craftsmanship  of the diamond and how it factors into the diamond’s brilliance.
