The ruby color chart consists of a wide range of hues, from the most intense reds to slightly pinkish or brownish shades. This spectrum allows for individual preferences and customization in jewelry design. In general, the closer a ruby's color is to a pure red hue, the more valuable it becomes.
However, the color of a ruby is not solely determined by its hue. Tone and saturation also play significant roles in defining its overall appearance. Tone represents the depth of color within the gemstone. Lighter tones tend to be less desirable, while medium to dark tones are considered more valuable.
Saturation, on the other hand, refers to the intensity or vividness of the ruby color. Rubies with high saturation display a rich and vibrant hue, making them highly sought after.

The Spectrum of Ruby Colors
Now let's explore the fascinating spectrum of ruby colors that can be found within the color chart. Each hue possesses its own unique charm and allure, making rubies a captivating gemstone for jewelry enthusiasts and collectors.
Pigeon Blood Red Rubies
Pigeon Blood Red rubies are renowned for their intense and vivid red color. These rubies possess a hue that closely resembles the blood of a pigeon, hence the name. This vibrant and fiery red hue is considered the most valuable and sought-after within the world of rubies.
When evaluating a Pigeon Blood Red ruby, gemologists look for a deep red hue with a balanced tone and high saturation. The interplay of these factors contributes to the aura of elegance and luxury that Pigeon Blood Red rubies exude.
Pinkish Red Rubies
Pinkish Red rubies exhibit a softer and more delicate hue compared to Pigeon Blood Red rubies. These rubies display a lovely blend of pink and red tones, creating a romantic and feminine appeal. Pinkish Red rubies are often associated with love and passion, making them a popular choice for romantic jewelry pieces.
When assessing the color of Pinkish Red rubies, gemologists examine the balance between pink and red tones. The ideal Pinkish Red ruby should possess a harmonious blend of these hues, creating a captivating and enchanting gemstone.

Gemologists evaluate Brownish Red rubies based on the balance between red and brown tones. The ideal Brownish Red ruby should maintain a sense of vibrancy while displaying a touch of natural warmth.
Factors Influencing Ruby Colors
Various factors contribute to the final color of a ruby. Understanding these influences is key to comprehending the vast range of colors within the ruby color chart.
Chemical Composition and Ruby Colors
The chemical composition of a ruby plays a significant role in determining its color. The presence of trace elements, such as chromium, iron, and titanium, directly impacts the color spectrum that a ruby can exhibit. Chromium, in particular, is responsible for the classic red hue that rubies are known for.
Different combinations and concentrations of these trace elements give rise to the diverse array of colors found within the ruby color chart. Gemologists analyze the presence of these elements to classify and assess rubies accurately.
Geographical Origin and Ruby Colors
The geographical origin of a ruby also influences its color. Rubies sourced from different regions exhibit varying shades and undertones. For example, rubies from Myanmar often display a vibrant and saturated red hue, while Thai rubies tend to possess a slightly pinkish tone.
Gemologists use knowledge of these geographical variations to identify and authenticate rubies. The ability to trace a ruby's origin based on its color characteristics adds value and authenticity to the gemstone.
Evaluating Ruby Colors
Evaluating the color of a ruby involves a meticulous examination of various factors. Gemologists consider not just the hue, but also the tone and saturation, as well as the impact of lighting conditions.
The Role of Hue, Tone, and Saturation
Hue, tone, and saturation work in harmony to define the color profile of a ruby. The hue represents the base color, while the tone indicates the depth or darkness of the hue. Saturation refers to the intensity or vividness of the color.
When evaluating a ruby, gemologists aim for a well-balanced combination of these three factors. Rubies with a pure red hue, medium to dark tones, and high saturation are typically highly valued due to their exquisite and captivating colors.
The Impact of Lighting on Ruby Colors
Lighting conditions play a crucial role in how we perceive and appreciate ruby colors. Natural and artificial lighting can affect the appearance and brilliance of a ruby. Different lighting sources may emphasize certain color characteristics while deemphasizing others.
Gemologists consider the impact of various lighting conditions when evaluating rubies, ensuring that the gemstones retain their color integrity and vibrancy across different environments and settings.
Ruby Color Treatments
In the world of gemstones, treatments and enhancements are common practices to enhance the color and overall beauty of a gemstone. Rubies are no exception.
Heat Treatment and Its Effect on Ruby Color
Heat treatment is the most widely used method to improve the color of rubies. This process involves subjecting the gemstone to high temperatures, which alters the arrangement of the ruby's crystal lattice, resulting in an enhanced color.
Heat treatment can intensify the red hue and remove undesirable color components, thereby transforming rubies into more vibrant and valuable gemstones. However, it is essential to disclose any treatments to maintain transparency and integrity within the gem trade.
Dyeing and Other Color Enhancement Techniques
In addition to heat treatment, dyeing and other color enhancement techniques may be employed to improve or alter the color of rubies. Dyeing involves the introduction of colored substances into the gemstone to enhance or manipulate its hue.
Gemstones that have undergone such color enhancement techniques must be disclosed to buyers, ensuring that they are making an informed purchase decision based on the true nature of the gemstone.
Understanding the intricacies of the ruby color chart is vital for gemologists, jewelry enthusiasts, and collectors alike. It allows for a deeper appreciation of the diverse and captivating world of rubies.
