A Ruby displaying asterism is known as a " Star Ruby ", and if transparent can be very highly prized. Star Rubies exists in six ray stars, though twelve ray stars are also known.
Rubies must be have good transparency to possess gem value. Opaque or semi-opaque Rubies have relatively little value, even if they display asterism.
The same Rutile inclusions that are responsible for asterism in certain Rubies can also decrease transparency and cause a hazy effect known as silk.
Though Ruby can be one the most expensive gemstones, it also comes in more dull opaque forms that are fairly inexpensive, and are often polished into cabochon s.

Although some rubies are incredibly valuable and can command very high prices, most rubies are considerably less expensive than diamonds of the same size.
This lower pricing makes a ruby an appealing alternative to a diamond for an engagement ring or other jewelry. For example, this 1.
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.
For example, this stunning As with emeralds , the most important factor when evaluating a ruby is its color. The deeper, and more intense the color, the more desirable the ruby.
The best ruby color is typically thought of as a deep, vivid red. However, rubies can look stunning in other colors, such as pink or brown-red.
Hue refers to where the ruby falls in the spectrum of other colors. Each ruby has a primary and secondary color. The primary color is red, and the secondary color is usually orange, purple or pink.
Some rubies mined from specific parts of the world are known to have certain secondary colors, such as rubies from Myanmar, which are known to have a slight purple secondary color.
Purple as a secondary color can actually be better in a ruby because it makes the red appear richer. Color tip: set a purplish red ruby in yellow gold , like they do in Burma.
The yellow color will neutralize the blue in the purple, making the ruby appear even more red. This brings us to our last color criterion, saturation.
Also, rubies that fluoresce glow in ultraviolet light can have even greater saturation. It should go without saying that if the color of a ruby is by far the most important factor, it would be crazy to even consider buying a ruby sight unseen.
This is the only way, for example, that gemologists can distinguish between pink sapphires and rubies. But it also leaves some room for error, so beware of these murky waters if someone is trying to sell you a ruby that looks a lot more to you like a pink sapphire!

Kievlenko , updated. List of gemstones by species. Rubies have a long history of enhancement. Unless the seller specifically states the stone is unheated, you should assume that some kind of heat treatment has been used.
