How to identify a ruby?

Its red color catches your eye at first glance. This stone belongs to the corundum family. Like sapphire, it forms from the crystallization of aluminum oxide or chromium. Its beauty seduces, and its durability is equally appealing. Its hardness stands at 9 on the Mohs scale, classifying it as an exceptional stone.

The origin of ruby

The mines of Myanmar (formerly Burma) are renowned for the quality of their rubies. Mining has taken place there for centuries. Burmese rubies remain famous for their color. Those from Ceylon reveal shades from light red to raspberry red. Those from Kenya lean more towards orange. Ruby is also found in other countries such as Thailand, Madagascar, Sri Lanka, Malawi, Tanzania, Greenland...

What are the value criteria for ruby?

The gemstone is subject to strict appraisal criteria. Since ruby falls into the category of precious stones, alongside sapphire, diamond, and emerald, experts analyze according to the 4 Cs rule: Carat (weight), Clarity, Color, and Cut.

The color of ruby

The first value criterion for this stone is its red color. The varying level of chromium or iron within the corundum determines its red hue. Variations range from light pinkish red to brownish red. Generally, this depends on its initial composition.

The most exceptional ruby, considered the most beautiful specimen ever recorded, is the gem with a "pigeon's blood" color. This intense red has a slight bluish undertone. Its translucency gives it its full beauty. Light passes through it with its transparent red. However, this stone is very rare.

Untreated and freshly mined rubies have unparalleled colors. They are not uniformized and reveal themselves in multiple dimensions. It is during cutting that the stone's beauty is enhanced. Also, note that rubies may have a secondary color; some are tinted with a slight hint of violet or orange.

Thus, the hue helps define the various color nuances specific to each stone. Each gem is authentic and unique due to these combinations and colorations.

The clarity of ruby

The rule determining a stone's clarity is not the same as for diamonds. Natural rubies are examined with the naked eye. This technique helps identify the gem's imperfections. Long years of experience confirm that no natural ruby is without inclusions. The less these inclusions are visible to the naked eye, the more valuable the stone. This is a reliable criterion for determining market price. For synthetic gems, the analysis is more in-depth.

Furthermore, saturation also comes into play when assessing a stone's value. This measurement determines the degree of clarity and color intensity. To this study is added the analysis of tone, focusing on the ruby's brightness: does it lean toward light or dark? The most valued rubies have medium-dark tones.

Cuts and shapes

Ruby can take various forms: pear, oval, round, rectangular, heart. This depends on the cut and the desired final result. As a precious stone, cutting is entrusted to a lapidary. They carefully cut the stone according to required standards and proportions. A professional's work brings out the best in the stone, favoring good color intensity and optimal light reflection.

To this study is added the analysis of tone, focusing on the ruby's brightness: does it lean toward light or dark? The most valued rubies have medium-dark tones.

Treatments

Several approaches can be used to treat ruby. The most common is high-temperature heating of the gem. The precious stone is heated in its rough state in a kiln at 1,300 °C. This method recrystallizes inclusions to make them invisible. The aim is to enhance the gem without altering its nature. All diamantaires accept this practice and use it on most rubies, as pure, rough red rubies are rare. This treatment is noted on the item's certificates.

You may also encounter lead glass-based treatments. These act deeply and transform the product for an artificial result.

Weight and price of ruby

This refers to the carat weight of the ruby. This measurement evaluates the gemstone's weight. Note that a high-carat gem commands an immeasurable price on the market. Generally, natural rubies of good quality do not exceed 2 carats.

Incidentally, carat for gemstones differs from gold carat, which defines the purity of the precious metal.

Rubies, with their captivating hues and exceptional clarity, have been dazzling gemstones for centuries. If you are lucky enough to own a ruby, Diamantaire Paris offers professional appraisal services using the international grading system. Ruby identification begins with its iconic red color, resulting from the crystallization of aluminum oxide or chromium, classifying it in the corundum family, like sapphire. A ruby's value depends on several criteria, including the 4 Cs (Carat, Clarity, Color, Cut). Burmese rubies are particularly renowned for their color, while those from Ceylon reveal shades ranging from light red to raspberry red.

In terms of clarity, it is accepted that no natural ruby is free of inclusions, and the less visible these inclusions are to the naked eye, the more valuable the stone. The ruby's color, especially intense "pigeon's blood" red, plays a crucial role in its evaluation. Common treatments include heating to improve transparency and color, while other techniques may alter the stone's appearance. Carat weight also strongly influences the ruby's market price.
