The 4 C’s of Diamonds

The 4 C’s of Diamonds

1. CLARITY

Clarity grades assess the number, size, relief, and position of inclusions and blemishes. Internally Flawless diamonds are extremely rare and command much higher prices per carat than gems with microscopic inclusions.

 


2. COLOR

The less color, the higher the grade. Even the slightest hint can make a dramatic difference in value. Diamond is the only gemstone that is valued for it’s lack of color!


3. CUT

Cut (proportions, symmetry, and polish) is a measure of how a diamond’s facets interact with light. A well cut diamond may cost up to 25% more per carat than a commercially cut diamond.

 

 


4.  CARAT WEIGHT

Rarity means larger diamonds of the same quality are worth more per carat. Smaller diamond crystals are more abundant than larger crystals. When color and clarity are high in a large diamond, the rarity is greatly increased.

Few people outside the gem industry realize the true nature of a gemstone’s journey from the mine to the counter of a store. Whether the gem is being offered to consumer’s at a traditional jewelry store’s counter, an internet shopping site, or a television broadcast the journey always involves a great deal of effort.  Tons of earth and countless hours of labor are needed to being a gem from mine to market.
