Gemstone Color: The Most Important Gemstone Factor.

The most important aspect of a gemstone is its color. Unlike diamonds, with cut as the most important factor, a gemstone’s color grading can account for 50% of its value. The color of a pure and high quality gemstone should never be extremely dark or light. Instead it should contain the true natural hue of the stone, together with small traces of complementing colors that are attributable to other minerals within the stone.

At E.S. Designs, we take great care to ensure that each of our gemstones has the highest quality spectrum of gemstone color characteristics: tone, hue, saturation, and distribution.

Gemstone Tone

Tone:
Tone refers to how deep - light or dark - the color actually is. The tone can be represented as light, dark, medium, medium-light, or medium-dark. The gemstone’s tone plays a critical role in its quality.

Gemstone Hue

Hue:
Every gemstone has a dominate natural color. Generally, the more pure a gemstone’s hue, the more valuable it is. For example, our sapphires vary in hue from greenish blue to purplish blue.

Gemstone Saturation

Saturation:
The saturation of a gemstone indicates the degree to which a stone is devoid of gray or brown colors. The more color-saturated a gemstone is, the more valuable it becomes. At E.S. Designs, our gemstones have saturated or vivid colors, meaning they only have slight traces of gray or brown.

Gemstone Cut and Satuation

Distribution:
Distribution refers to how uniformly the color is spread throughout the body of the gemstone. A more uniform color would generally mean a higher value.
