It is important to know how much your diamond is worth. This might prove necessary especially you want to buy one.

Diamond’s worth is predominantly affected by the 4Cs. These includes the carat weight, color, clarity, and cut quality.

Definitely one will be looking for a diamond that have a great worth but not just a fake and worthless stone.

The Four Cs describe the individual qualities of a diamond, and the value of an individual diamond is based on these qualities.


The Color

The differences in color can intensely affect diamond’s value. Even the slightest indication of color can make a dramatic difference in value.

Diamonds range from colorless to light yellow and brown fall within the normal color range. Among all these, white diamonds are the rarest. So they’re the most prized. They set the standard for grading and pricing other diamonds in the normal color range.

At the GIA Laboratory, diamonds are color graded under controlled conditions by comparing them to round brilliant diamonds of known color, called master stones.

The GIA D-to-Z scale is the industry standard for color-grading diamonds. Each letter represents a range of color based on a diamond's tone and saturation.

The Clarity

Clarity is the relative absence of inclusions and blemishes.

Diamonds have internal features, called inclusions, and surface irregularities, called blemishes. Clarity characteristics might have a negative influence on a diamond’s value.

Clarity’s influence on value is directly related to the concept of rarity. Flawless is the top grade in the GIA Clarity Grading System.

Flawless diamonds are very rare—so rare, in fact, that it’s possible to spend a lifetime in the jewelry industry without ever seeing one, and they command top prices.

There are 11 clarity grades in the GIA clarity grading system. They are Flawless, Internally Flawless, two categories of Very, Very Slightly Included, two categories of Slightly Included, and three categories of Included.

These terms were shortened to the initials VVS, VS, SI, and I. The abbreviations eventually gained acceptance throughout the international diamond community.

The Cut

A beautifully finished diamond is dazzling. When a diamond interacts with light, every angle and every facet affects the amount of light returned to the eye. This is what gives it its face-up appearance. The more dazzling it is the higher the value.

The Carat Weight

Diamond weights are stated in metric carats, abbreviated “ct.” One metric carat is two-tenths (0.2) of a gram—just over seven thousandths (0.007) of an ounce. One ounce contains almost 142 carats. A small paper clip weighs about a carat.

The metric carat is divided into 100 points. A point is one hundredth of a carat.

Diamonds are weighed to a thousandth (0.001) of a Carat Weight and then rounded to the nearest hundredth, or point. Fractions of a carat can mean price differences of hundreds—even thousands—of dollars, depending on diamond quality.
