Qualifying a diamond: The Third of 4C’s (Color)

Color
Diamonds act as prisms and divide light into a spectrum of colors and reflect this light as colorful flashes referred to as fire.  The more colorless a diamond is the more colorful the fire will appear.Grading of a diamond’s color is based on the Gemological Institute of America (GIA) Color Scale of D-Z which was founded in 1953.

Since nothing is entirely perfect, keep in mind that there are diamonds that can come outside of this normal color range created by the GIA.  The stones which fall under this category are referred to as fancy-colored diamonds and come in almost any color imaginable.  A famous example of a “fancy-colored” diamond is the Blue Hope diamond which is on display at the Smithsonian Institute in Washington.

The fluorescence of a diamond is created when the exposure to ultraviolet (UV) light gives diamonds a distinctive glowing blue coloration.  Being that it is not directly related to color the fluorescence may vary from very weak to very strong.

Odly enough, the GIA chose to start the grading system with a “D” instead of an “A”?  this was done  because multiple other systems existed before they created their grading system.  One system that existed was based on an A, B, C, etc. format and another was based on an agricultural type of format: A, AA, etc.  So, in an effort to avoid any confusion  the GIA simply decided to start out new by not using previous terminology to avoid  this, their grading scale begins with “D”.

Tomorrow we will cover the fourth and final of the 4C’s in our diamond education series. Its always a good thing to know a little something especially about jewelry. Please feel free to like our page and leave any questions or comments.
