‘The Right Green’ for Emerald

If green stands for prosperity, then ‘Emerald Green’ is the most prosperous green ever. While there is a known fact that emeralds are green in color, not everyone can easily grade it’s value based on color. Color is the most important value determinant in colored gemstones. Like all other gemstones, an emerald's color is scaled based on three factors, namely hue, tone and saturation. The most appropriate description of ‘Emerald Green’ would be like fresh young green grass. It is a vibrant and highly concentrated green with a medium to medium dark tone.

Emerald Hue:

We all know that the main hue of emerald is green. However, what makes some emeralds appear warm and others cold are secondary hues and overtones. Secondary hues may be blue or yellow. While some emeralds are pure green, others may be bluish green or yellowish green. While yellow as an overtone makes them appear warm, a blue hue can give a cold response. Their ideal hue may vary based on individual preference and design requirements, but when we discuss in terms of trading value, vivid green is considered by far the best.

Emerald Tone:

Tone refers to lightness or darkness of the color. A high quality emerald should be medium to medium dark in tone. While emeralds in lighter tones look pale, some emeralds are too dark and have more of a blackish tone, which are not preferred by the public.

Emerald, Saturation:

Saturation refers to the intensity or richness of the hue. In simple terms, the higher the saturation, the more praised the color. But when color is excessively intense, they will appear blackish or grayish, destroying the original hue of the gemstone. Gray saturation is also referred as masking. Masking is a negative factor that depreciates the quality of emeralds. Therefore, while intensity of color is important, too many can take away the value.

Potential Color:

Artistry cutting or faceting can bring out the potential color of the gemstone. A deep cut usually darkens the color, whereas a shallow cut lightens the stone. Presence of large windows and excessive black tinted patches result in the facets not utilizing the gemstone's potential color. Therefore, a deep cut stone is not only color rich, but easier to mount on jewelry, giving us the best results.
