Colors of gems
Gems come in every color of the spectrum. While sapphires, rubies and
emeralds are what come to mind first when one thinks of a colored gem,
there are so many other beautiful colored gemstones to consider. Even
among gems normally associated with one color, there are gradations and
variations to them. A sapphire, for example, comes in many different
hues of blue, depending on where it・s from. But sapphires can also come
in pink, yellow and green.
The most highly prized colored gems are in the very deepest, richest
hues of the color. While sapphires can range from pale blue to
near-black, the most valuable are a rich, deep blue. The same holds
true for rubies. While they too can range in color from pale to very
dark and murky, the most highly-valued color is what・s called pigeon・s
blood, a deep blood-red ruby that is mined in what was once known as
Burma.
The most expensive emeralds are a deep green, although emeralds
themselves come in a broad spectrum of hues, from yellow-green to
blue-green. All colored gems, and clear gems, depend on expert cutting
and polishing to showcase the colors in all their subtleties and
brilliance.
Generally the deeper and richer the color, the more valuable the stone.
The best amethysts will be a dark, royal purple. A lighter-colored
amethyst simply isn・t as valuable.
But many people prefer these lighter or darker gradations in color.
And, they tend to be more affordable. A slightly lighter-colored
amethyst is much easier to obtain than the ：ideal； color, but is still
a beautiful gemstone.
Oddly enough, diamonds are rated by how colorless they are. The less
color, the higher the grade of diamond. Unless of course it・s a defined
color such as a pink diamond or a canary diamond. These are almost as
highly prized as a near-colorless diamond
