The essence of emotion.

Diamonds are the crystal essence of emotion. They capture the light and release it, one facet at a time. Carson Jewelers understands the power of diamonds—nothing else can express that emotion. We can help you choose a diamond that will be cherished for a lifetime. From 18karat gold to platinum, you’ll find an impressive selection of possibilities.

We are one of the region’s only American Gem Society members. We have the area’s only AGS-accredited gemological and diamond grading laboratory. Our staff will patiently show you the many facets of diamonds, including the “4Cs” of cut, color, clarity and carat. (For more information on the 4Cs, follow the links above.)

Cut refers to the proportions, symmetry and polish of a diamond. It also refers to the shape outline of the diamond (i.e. round, oval, marquise, pear, princess, Hearts on Fire dream, emerald)

The modern round brilliant cut contains 58 facets.

Proportion and finish are responsible for Brilliancy (return of white light from within the diamond), Dispersion (break up of white light into spectral colors as it exits from the diamond - also called "fire"), and Scintillation (reflection of white light from facets). The degree of Fire and Brilliance of a diamond display depends primarily on how well the stone has been cut.

An ideal cut diamond is a round brilliant cut that is fashioned with a very specific set of proportions, which have been proven to yield the best balance of brilliancy and dispersion. Ironically only a small number of diamonds are cut to these proportions.

For a more detailed description of cut, please see the American Gem Society's web page.


Color refers to the body color of the diamond. Most diamonds have a slight trace of yellow, brown or gray. With the exception of naturally "Fancy Color" diamonds, the more colorless a diamond is, the greater is its value.

GIA grading scale for colorless to light ranges from D to Z. Diamonds range from colorless, which is the rarest and most valuable, to yellowish, with a spectrum of shadings in between.

Colorless Near Colorless Faint Yellow Very Faint Yellow Light Yellow

Fancy color diamonds can be naturally colored or treated. Diamonds of natural color are also rare and can be high in value. Colors might include purple-red, red, blue, pink, green, yellow, champagne, and black.

For a more detailed description of color, please see the American Gem Society's web page.


Clarity refers to Inclusions (internal characteristics) or Blemishes (external characteristics) observed under 10X magnification. The Clarity is based on the size, nature, number, position, and color of the characteristics. The greater the Clarity of the diamond the more rare the stone is and therefore the greater the value.

GIA scale ranges from Flawless to Imperfect (see below for description)


Metric carat equals 0.20 (one fifth) of a gram. Point is used to refer to proportion of a carat (one point equals 1/100 of a carat; 50 points equal 0.50 ct). Because diamonds are so rare, the larger the stone the greater the price per carat (all other things equal).
