What Affects A Diamonds Worth?

Depending on the characteristics of a diamond, it can be worth hundreds or hundreds of thousands of dollars. Much like houses or cars, there is not one universal price for a diamond as there are a multitude of factors that affect the price. Diamonds come in an array of shapes, sizes and colors with varying external and internal qualities.

The basics of diamond grading are the 4 C’s. These are:

  1. Color: Refers to how much color, or lack thereof, a diamond shows. These grades range from D to Z, with D being colorless and Z a light yellow. Colorless diamonds are considered more valuable as they allow for a greater passage of light through a diamond, creating a sparkling appearance.
  2. Clarity: Refers to the amount of internal and external marks on a diamond, known as inclusions and blemishes respectively. These grades range from FL to I3, with FL being flawless and I3 being visibly flawed to the naked eye. A diamond may look flawless to the naked eye, but damages in the diamond can be seen upon further inspection with a loupe.
  3. Carat Weight: Refers to the weight of the diamond in carats, abbreviated to ct.
  4. Cut Grade: Refers to the cut quality and proportions of a diamond. These grades range from Excellent to Poor. Excellent cuts are desirable because they best reflect light.

In addition to the 4 C’s, there is other criteria that affect a diamonds worth. These factors include:

  • Shape: Diamonds are cut into various shapes with the most popular being the round brilliant. Fancy cuts include: princess, cushion, heart, pear, radiant, oval and emerald cut. The value of fancy cut diamonds fluctuate depending on market trends.
  • Fluorescence: Refers to how much a diamond glows when under ultraviolet light. These grades range from None to Very Strong. The presence of fluorescence typically has a negative impact on diamond value.
  • Symmetry: Refers to how well aligned the facets of a diamond are including its table, culet, crown and girdle. These grades range from Excellent to Poor.
  • Polish: Refers to the degree of smoothness for each facet of a diamond. When diamonds are cut and polished, microscopic surface defects may be created. These grades range from Excellent to Poor.
  • Treatments: Diamond can be treated to artificially improve their color or clarity. Fracture filling, HPHT and clarity enhanced considered less valuable than their natural counterparts.
