Understanding Diamond Color and Grading

The video tutorial explains the concept of diamond color, one of the four C's of diamonds, which actually refers to the lack of color. It details the diamond color grading scale from D to Z, where D is colorless and Z is visibly colored. The video also discusses fancy colored diamonds, which are rarer than white diamonds. It explains how natural diamonds get their colors through unique bonds with elements like nitrogen and boron, or through distortions caused by radioactivity or high temperature and pressure. Finally, it provides guidance on choosing the right diamond color for purchase, emphasizing that most natural diamond jewelry contains diamonds between the D to M grade.
