Every gemstone has its own color. A blue sapphire is not simply a blue sapphire.
It may be a midnight blue, a deep darkish blue or a light royal blue. There are
also pink, yellow, purple, black, orange sapphires and other shades.
A ruby is not merely red. It may be pigeon blood red, pinkish red or violet red.
And emeralds are found in a variety of colors from grass green to soft green, olive
green darkish green and more.
The color of a gemstone is determined by three separate factors: hue, tone and saturation.
Hue - Dictionary Definition
- A gradation or variety of a color; tint: pale hues
- The property
of light by which the color of an object is classified as red, blue, green or yellow in reference to the spectrum
- Color: allhues of the rainbow
- Form of appearance
The hue of a gemstone has an impact on its value. Some shades are more sought after
than others, some are rarer, and some, with varying measures of brown or grey tinge
are considered better value for money for those on a more limited budget.
Tone - Dictionary Definition
- A quality
of color with reference to the degree of absorption or reflection of light; a tint
or shade; value
- The distinctive quality in which colors differ from one another. In addition, these differences are indicated through tint, shade, and a slight modification of any given color, including hue: green with a yellowish tone.
We use tone to indicate the intensity of color. Tones can range from clear (without
color) to black. When we add
light, dark, darkish
or other adjectives to our color descriptions, we are referring to the tone of the
color being described.
For example, if you are looking for a royal blue sapphire you may find stones in
our collection described as light royal blue, medium royal blue, or dark royal blue
depending on their tone.
Saturation - Dictionary Definition
The degree
of chroma or purity of a color; the degree of freedom from admixture with white.
A gemstone with excellent saturation reflects a pure color, without brown or grey
hues. Our top gemstones are rated with either excellent or very good saturation
for a vibrant, bright color.
