The fourth in the diamond color rainbow, green diamonds are another exceptionally rare hue. These rare beauties are created by radiation, and attempts to trace their origin are often inconclusive as a result.  

The most famous and largest natural green diamond is the 41-carat Dresden Green. The Dresden Green is an exceptional diamond because its green color is evenly distributed throughout the body of the stone. While most green diamonds owe their color to surface “skins,” the Dresden is uniformly green.

Purple diamond.

The sixth color in the diamond rainbow, purple diamonds are also quite rare. The diamond ore is exposed to hydrogen, creating a purple hue. 

The Royal Purple Heart is one of the most famous purple diamonds; A 7.34-carat Fancy Vivid Purple I1 clarity diamond. The Royal Purple Heart is aptly named as it has both Vivid Purple color and is a heart shape.  The heart shape brings out the brilliance of the natural purple color of the diamond.

Diamonds are found in almost every color of the rainbow, but most diamonds will have tints of yellow or brown. Typically, the term Diamond Color refers to the absence of color, which is a quality marker along with the other 4Cs of Diamond ClarityDiamond Carat Weight, and Diamond Cut. This tutorial focuses on fancy-colored diamonds. Brown and yellow diamonds that exhibit more color than the Z grade within the D-Z color scale are known as fancy colors. Since most diamonds have a bit of yellow or brown, other colors outside those hues are called fancy colors. This includes pink, blue, green, black, red, and orange diamonds.

Celebrating the rainbow is a great way to add some new bling to your life!
