Two rubies may look similar at first glance, yet their prices can be very different. One of the biggest reasons is color.
Ruby is known for its beautiful red appearance, but not every red ruby looks the same. Some have pink, purple, orange, or brown undertones. Gemstone experts consider factors such as hue, tone, and saturation when evaluating ruby color.
In this guide, we’ll explore the different colors of rubies, understand why pigeon blood red is highly prized, and learn which ruby color is traditionally preferred for astrological purposes.
What Color Is Ruby?
Ruby is the red variety of the mineral corundum. Its red color is mainly caused by trace amounts of chromium.
The primary characteristics of ruby color include:
- Main color: Red
- Color-causing element: Chromium
- Possible secondary tones: Pink, purple, orange, or brown
- Gemstone family: Corundum
- Traditional astrological name: Manik
For a gemstone to be classified as ruby, red must remain the dominant color. If the stone appears predominantly pink, it may be classified as pink sapphire under the standards used by some gemological laboratories.
The word ruby comes from the Latin word ruber, meaning red.
Different Colors of Rubies
Rubies can vary considerably in their appearance. Their color is generally described using hue, tone, and saturation.
Here is a simple comparison:
| Ruby Color | Appearance | General Desirability |
|---|---|---|
| Pigeon Blood Red | Vivid, pure red with balanced medium tone | Highly prized |
| Vivid Red | Bright and lively red | Highly desirable |
| Pinkish Red | Red with a noticeable pink influence | Depends on quality |
| Purplish Red | Red with purple undertones | Depends on quality |
| Orangish Red | Warm red with orange undertones | Depends on quality |
| Brownish Red | Red with noticeable brown influence | Generally less desirable |
Note: Color alone does not determine the value of a ruby. Clarity, size, origin, treatment, transparency, cut, and overall quality also play important roles.
Which Ruby Color Is Considered the Best?
Among fine-quality rubies, pigeon blood red is traditionally regarded as one of the most desirable color descriptions.
A highly attractive ruby generally has:
- A vivid red hue
- Strong color saturation
- A balanced medium to medium-dark tone
- Good brightness and visual appeal
- Minimal distracting secondary color
However, the term “pigeon blood” can be used differently across the gemstone trade and laboratories. Therefore, buyers should consider the actual appearance and laboratory documentation rather than relying on the name alone.
How Experts Judge Ruby Color
Ruby color is usually understood through three important characteristics: hue, tone, and saturation.
1. Hue
Hue describes the basic color family of the gemstone.
Red is the primary hue of ruby, while secondary influences may include:
- Pink
- Purple
- Orange
- Brown
A strong, attractive red with minimal unwanted secondary color is generally considered desirable in fine ruby.
2. Tone
Tone describes how light or dark the ruby appears.
A ruby that is too light may appear less intense, while an excessively dark ruby may lose brightness. A balanced medium to medium-dark tone is often preferred for fine-quality stones.
3. Saturation
Saturation refers to the strength or intensity of the color.
A ruby with strong, vivid red color can appear more lively than a stone that looks dull, grayish, or overly brown.
This is why two rubies of the same size can have very different appearances and market values.
Why Are Rubies So Valuable?
High-quality natural rubies are relatively rare, particularly stones that combine strong color with good clarity and desirable size.
However, color is not the only factor that determines ruby value.
Other important factors include:
Clarity
Natural rubies commonly contain inclusions. The type, number, size, and visibility of inclusions can affect appearance and value.
Carat Weight
Larger rubies of fine quality are considerably rarer. As a result, the price per carat can increase significantly with size and quality.
Origin
Some ruby-producing regions have strong reputations in the gemstone market. Myanmar, Mozambique, and Vietnam are among the notable sources of natural rubies.
However, origin should be considered together with the actual quality of the individual gemstone.
Treatment
Heat treatment is common in the ruby market. It can improve the color and appearance of certain stones.
Untreated rubies with excellent natural color are comparatively rare and may command a premium. Buyers should always check the gemstone report for treatment information.
Overall Quality
A ruby's transparency, brilliance, cut, color, clarity, treatment, and size all contribute to its overall appeal and value.
Therefore, the reddest ruby is not automatically the most valuable ruby.
Does Ruby Origin Affect Its Color and Value?
Yes, origin can influence both the appearance and market perception of a ruby, but it should not be the only factor considered.
The Mogok region of Myanmar has a long history of producing highly regarded rubies. Mozambique has also become an important source of ruby, with stones that can display rich and vivid red colors.
When buying a ruby, focus on the actual gemstone quality and reliable certification, rather than choosing a stone based solely on its origin.
Which Ruby Color Is Best for Astrology?
In Vedic astrology, ruby is traditionally known as Manik and is associated with the Sun (Surya).
For traditional astrological use, a bright to vivid red ruby is generally preferred. The suitability of a ruby, however, is traditionally determined according to an individual's birth chart rather than color alone.
When considering a ruby for astrological purposes, traditional guidance generally focuses on:
- Color: Bright or vivid red
- Tone: Balanced rather than excessively dark
- Appearance: Attractive and naturally formed
- Quality: Good overall clarity and transparency
- Astrological suitability: Based on the individual's birth chart
A gemstone should not be selected solely because it is expensive or has a particular color name. If you are considering ruby for astrological purposes, consult an experienced astrologer for personalized guidance.

Ruby for Astrology: What Should You Check?
If you are buying a ruby specifically for astrological purposes, consider these points:
- Check whether the stone is natural or laboratory-created.
- Ask whether the ruby has been treated.
- Check the gemstone certificate.
- Examine the color under natural lighting.
- Look at the gemstone's transparency and overall appearance.
- Consider the stone's weight and quality.
- Consult an astrologer before wearing it for astrological purposes.
The right gemstone should be selected based on both gemological quality and traditional astrological suitability.
FAQs About Ruby Colors
1. Do rubies look different under different lighting?
Yes. Ruby can appear slightly different under different lighting conditions. Some natural rubies may also show fluorescence, which can influence their visual appearance.
For a better evaluation, examine the gemstone under natural daylight as well as indoor lighting.
2. Does heat treatment permanently change a ruby's color?
Yes. Heat treatment can permanently improve the appearance of some rubies by enhancing color or reducing the visibility of certain inclusions.
Heat-treated rubies are common in the market. Untreated rubies with excellent natural color are rarer, so always check the laboratory report for treatment information.
3. What is the difference between a natural and synthetic ruby?
A natural ruby forms naturally within the Earth.
A synthetic ruby is created in a laboratory but has essentially the same chemical composition and crystal structure as natural ruby.
They can look very similar, but their origin, rarity, and market value are different.
4. Can a ruby's color fade over time?
A natural ruby's color normally does not fade with regular wear.
However, dirt, oils, or residue can make the gemstone look dull. Scratches or surface damage can also affect its appearance.
For valuable gemstones, professional cleaning and inspection are recommended.
5. Is pigeon blood red always the most valuable ruby?
Not necessarily. Pigeon blood red is a highly prized color description, but ruby value depends on several factors, including color, clarity, carat weight, origin, treatment, transparency, and overall quality.
A ruby should therefore be evaluated as a complete gemstone rather than by color name alone.
Final Thoughts
Ruby is one of the most fascinating gemstones because its color can range from bright vivid red to shades influenced by pink, purple, orange, or brown.
Among fine-quality stones, vivid red and pigeon blood red are particularly sought after. However, color is only one part of a ruby's value.
If you're buying a ruby for astrological purposes, don't choose it based on appearance or price alone. Consider its authenticity, treatment, certification, gemstone quality, and traditional astrological suitability.
