Diamonds 101

Posted on December 08, 2011 by Barbara Polinsky | 1 Comment

Every diamond is as unique as the individual that wears it and weighing the pros and cons of a particular stone can be confusing.  Here's a quick overview of the 4C's 

CUT
The most identifiable of the four C's and the only grade that humans actually play a role in influencing. The cut of a diamond does not only refer to the shape but the facet design, finish and proportions of the diamond. A diamond that is well cut will radiate light and brilliance because the facet angles are optimum. Vintage diamonds can be an exception to this rule.

COLOR
The color of a diamond refers to the hue and saturation of the intensity or lack of color in a diamond. Color is graded in shades of yellow, brown and gray and comes from different levels of nitrogen below the surface of the earth; little to no nitrogen produces colorless diamonds. High levels of nitrogen produce yellow and brown hues. Color is graded in letter classifications from colorless (D-E-F), near colorless (G-H-I-J) and degrees of yellow and brown (K to Z). Some of the most rare colors occur in fancy, vivid shades of yellow, pink and even blue.
