Very high-end rubies can be far more expensive — in some cases, either as expensive or more expensive than diamonds of the same size.

Like diamonds, rubies are assessed using certain quality factors. Of these, the most important, by far, is color. The stronger and more intense the color, the more valuable the ruby.

Finally, like with all gemstones, the carat weight of a ruby plays a role in its value, with a larger ruby commanding a higher value than a smaller one.

An exceptionally high-quality ruby that combines rich, natural color with other quality factors is exceptionally rare and often worth an incredible amount.

Each ruby has a primary and secondary color. The primary color is red, and the secondary color is usually orange, purple or pink.
