A diamond’s color is an important element of its quality. In a white diamond, the less body color present, the greater the value of the diamond. The GIA grades diamonds on a scale of D (colorless) to Z (noticeable color).
The predominant color you see in a diamond is yellow, which is caused by the trace element nitrogen.
Clarity refers to the presence of imperfections, flaws and blemishes inside or on the surface of a diamond.
The GIA grades diamond clarity under 10X magnification on a scale that ranges from Flawless (FL) to I2-3 (Included). Diamonds with the least amount of flaws having the highest clarity grading.
A diamond’s clarity has a significant impact on its value.
The cut of a diamond influences how effectively it reflects light. Well-cut diamonds appear fiery and brilliant and allow light to enter the stone and be reflected around the facets before exiting the stone through the top. Poorly-cut diamonds can appear lifeless and dark, despite their clarity or color grade.
Not only do well-cut diamonds appear more brilliant, they also tend to appear larger than other diamonds of the same carat weight.
