A diamond's color is determined by a trained professional who compares the color to a diamond in a "Master Set" whose color has been predetermined by an independent authority such as the Gemological Institute of America (GIA).

All diamonds will have inclusions (crystals, feathers, carbon, etc.) under enough magnification. The diamond industry has defined the standard as 10X magnification. he clarity of the diamond can vary from Flawess to I,3not all inclusions will affect the sparkle and beauty of a diamond, they do affect its value and price.
