The Color of Gems

Nowadays, you may find 10 green gemstones to upgrade your jewelry box. But primarily, there are three main colors: red, green, and blue. Then there are the secondary colors, which are the result of blending basic colors like purple, orange, or green. There are many colors to choose from, including blue-violet and yellow-green.


Saturation refers to the perception of grays of the same brightness. Grays are generally characterized by zero saturation. The theory goes that complete saturation means there is no gray.


A color that is believed to be green or yellow and/or purple. It implies that gray, black, and white are not imbued.


Tints are a color that is mixed with white. Tints are less saturated and lighter than colors without white.

The color grade refers to the strength of the main colors relative to other colors in the stone. For example, a 100% blue grade would mean that the main color is clear and there are no violets or purples in the stone. These things will be reflected in the complimentary gemstone report.
