Different Colors of Rubies: Which Color Is Best & Most Valuable?

Imagine two red gemstones sitting side by side at a jeweler's counter. Both are called rubies, yet one costs many times more than the other. What makes the difference? In most cases, it starts with the color.

But color is more than simply choosing the brightest red. Gemologists assess a ruby by different characteristics, which can have a major effect on appearance and value.

In this blog, you will learn how experts judge ruby color, how different shades compare, why pigeon blood red is so prized, and which color is traditionally preferred for astrological wear.

What Color Is Ruby?

Ruby is a red gemstone made of the mineral corundum. Trace amounts of chromium give ruby its characteristic red color.

Here is what you need to know:

• Main color: Red

• What creates the red: Traces of chromium

• Appearance: Red, with possible pink, purple, orange, or brown influences.

• Classification: Red must remain the dominant hue for corundum to be classified as ruby.

• Pink sapphire boundary: If pink becomes the dominant hue, gemological laboratories often classify the stone as pink sapphire.

The name of this stone comes from the Latin word “ruber,” meaning “red” In simple terms, ruby is the red variety of corundum, but its exact appearance can vary in hue, tone, and intensity.

Rubies can show noticeable differences in hue, tone, and intensity. Here is a simple comparison of the main shades you may encounter and their general position in the value range.

Which Ruby Color is Considered The Best?

Pigeon blood red is often considered the most desirable ruby color. It is prized for its combination of:

• Vivid red hue: The stone has a strong, lively red appearance.

• Medium tone: It is neither excessively light nor overly dark.

• Strong saturation: The red looks rich and intense rather than dull or washed out.

How Experts Judge Ruby Color: Hue, Tone, and Saturation

Simply being red does not tell you how good a ruby is. Experts look at hue, tone, and saturation to describe the stone more precisely. Understanding these three characteristics makes it easier to compare ruby colors.

Hue:

Hue (color family) tells you what color you are seeing. Red is the main hue of ruby, while pink, purple, orange, or brown may appear as secondary influences. Generally, a clean red with little secondary color is more desirable than a stone dominated by another hue.

Tone:

Tone tells you how light or dark the ruby appears. A medium to medium-dark tone is commonly preferred for fine-quality ruby. If it becomes too dark, the stone can lose brightness, and if pink becomes the dominant hue, the stone may be classified as pink sapphire rather than ruby, depending on the laboratory’s standards.

Saturation:

Saturation describes how strong and vivid the color looks. A ruby with strong, vivid red tends to be more attractive than one that looks grayish, brownish, or washed out. As a result, two rubies of the same size can have very different values.

Why Are Rubies So Expensive?

Fine-quality rubies are rare, which makes them valuable. While color is one of the most important factors, a ruby's price is also influenced by its clarity, carat weight, origin, treatment, and overall quality.

Does Color Alone Determine a Ruby's Value?

No. Color is important, but not the only factor. For example: 

• Clarity: Fewer or less noticeable inclusions can increase value, although some inclusions are common in natural rubies and do not necessarily reduce their desirability.

• Carat weight: Larger fine-quality rubies are considerably rarer, so price per carat can increase as size increases.

• Origin: Certain origins have a strong reputation in the ruby market, but origin should be considered alongside the stone's actual quality and laboratory report.

• Treatment: Untreated rubies with fine natural color can command a premium because they are rarer. Heat-treated rubies are also widely available and can still be valuable depending on their quality. 

• Overall quality: Cut, transparency, brilliance, and the combination of color and clarity can all influence the final value.

Therefore, a ruby with an excellent color may not automatically be worth more than every other ruby.

Does ruby origin affect its color and value?

Yes, but origin should not be used as the only measure of quality. Myanmar's Mogok region is historically known for exceptional rubies, while Mozambique and Vietnam are also important sources of ruby.

For example, Mozambique rubie can display rich, vivid red colors and are now an important part of the ruby market. So, when comparing rubies, look at the actual stone and its certification rather than choosing based on origin alone.

Which Ruby Color Is Considered Best for Astrology?

A bright red ruby, traditionally preferred for astrological wear, is known as Manik in Vedic astrology. Manik refers to ruby as a broad term, while “pigeon blood” describes a rare, premium ruby with a pure, vivid red hue historically associated with Myanmar.

When choosing a Manik, consider:

• Color: Bright to vivid red

• Tone: Medium, rather than excessively dark

• Quality: Clear and well-formed, with good overall appearance

• Suitability: Traditionally selected according to the individual's birth chart

A dark, dull, or strongly brownish ruby is traditionally considered less desirable for astrological use.

FAQs

1.) Do rubies look different in different lighting?

Yes, a ruby can look slightly different under different lighting. Fluorescence may make the ruby’s red appear more lively under certain lighting conditions, while Pleochroism can cause subtle differences in color intensity or hue when the stone is viewed from different directions. Check the stone under natural daylight before judging its color.

2.) Does heat treatment change a ruby's color permanently?

Yes. Heat treatment can permanently improve the appearance of some rubies by enhancing color and, in certain cases, reducing the visibility of inclusions. It is common in the ruby market, but Untreated rubies with fine natural color are generally rarer and can command a premium. Always check the laboratory report to understand whether the ruby has been treated.

3.) What is the difference between natural and laboratory-created (synthetic) rubies?

Natural rubies form naturally within the Earth, while lab-created rubies are made under controlled conditions. Both have essentially the same chemical composition and can look very similar. However, natural rubies are rarer, while lab-created stones are comparatively more affordable.

4.) Can a ruby's color fade over time?

No, a natural ruby's color does not normally fade with regular wear. If a ruby looks dull, surface dirt or residue may be reducing its brilliance. Scratches or other damage can also affect its appearance and should be assessed by a professional. Gentle cleaning can restore surface brightness, while a professional should check deeper scratches or damage.
