Rubies, known for their fiery red color, have long been cherished as one of the most precious gemstones in the world. While all rubies are considered valuable, certain types stand out as exceptionally rare and highly sought after by collectors and enthusiasts. In this article, we will explore the rarest types of rubies, their distinctive characteristics, and the factors that contribute to their scarcity. From the legendary Burmese “Pigeon’s Blood” rubies to the mesmerizing Star Rubies, we will delve into the fascinating world of these extraordinary gemstones.

Understanding Ruby: A Brief Overview

Rubies are a variety of the mineral corundum, with their vibrant red color attributed to the presence of chromium. They are part of the corundum family, which also includes sapphires in all other colors. Rubies have a remarkable hardness, scoring a 9 on the Mohs scale, second only to diamonds. The intense red color of rubies has been associated with passion, power, and vitality throughout history, making them highly desirable gemstones.


The Rarest Types of Rubies

Let’s explore some of the rarest types of rubies that have captured the fascination of gemstone enthusiasts worldwide:


Burmese “Pigeon’s Blood” Rubies

Burmese rubies, especially those referred to as “Pigeon’s Blood” rubies, are considered the epitome of rarity and beauty. These rubies are characterized by their exceptional hue, which exhibits a pure, vivid red color with a slight undertone of blue. The name “Pigeon’s Blood” is derived from the analogy to the rich, vibrant red color seen in the blood of a freshly killed pigeon. Burmese rubies are highly coveted for their intense color saturation, which is often unrivaled by rubies from other locations.


Star Rubies

Star Rubies are renowned for their mesmerizing asterism, a star-like phenomenon that appears on the surface of the stone when properly cut and polished. The star effect is caused by intersecting needle-like inclusions known as rutile, which create a captivating optical phenomenon known as asterism. The star typically exhibits six rays, but rare specimens may display twelve rays, adding to their allure. Star Rubies are considered rare due to the precise alignment and quality of the rutile inclusions required to produce the star effect.

Alexandrite-like Color Change Rubies

Alexandrite-like color change rubies are exceptionally rare and valued for their remarkable color-changing properties. These rubies exhibit a unique phenomenon known as color change, where their color shifts under different lighting conditions. In daylight or fluorescent lighting, they display a purplish-red or pinkish-red hue, while under incandescent lighting, they transform into a vibrant purplish-red or raspberry-red color. The rarity of these rubies lies in their ability to exhibit a significant and distinct color change, similar to that of alexandrite, a highly coveted gemstone renowned for its color-shifting properties.

Trapiche Rubies

Trapiche rubies are exceedingly rare and prized for their distinctive and mesmerizing “wheel” or “spoke” pattern. The name “trapiche” is derived from the Spanish word for “cartwheel,” referencing the radial pattern reminiscent of a cartwheel. These rubies exhibit a six-rayed pattern formed by intersecting dark mineral inclusions, typically hematite or magnetite. The rarity of trapiche rubies lies in the precise formation of these inclusions, which require specific geological conditions and growth processes.

Pink Rubies

While red is the most renowned and sought-after color for rubies, pink rubies are an exceptionally rare variety that appeals to collectors and connoisseurs. Pink rubies exhibit a delicate and soft pink hue, with varying degrees of saturation and undertones. Their rarity stems from their scarcity in nature and their unique coloration, which differs from the typical red hues associated with rubies.

Factors That Influence Rarity

Color Intensity:

The intensity of the pink color is a crucial factor in determining the rarity of pink rubies. Vibrant, richly saturated pink hues are considered more desirable and command higher prices. The presence of secondary colors, such as purple or orange, can influence the rarity and value of pink rubies as well.


Like other gemstones, the clarity of pink rubies plays a significant role in determining their rarity. Rubies with minimal or no visible inclusions are considered more valuable. The presence of clarity-enhancing treatments, such as heat treatment, can affect the rarity and value of pink rubies.


Larger pink rubies are rarer and more valuable than smaller ones. As the size increases, the rarity and price of pink rubies tend to escalate exponentially. Finding large, high-quality pink rubies is exceptionally rare, contributing to their exclusivity and value.


The origin of a pink ruby can greatly impact its rarity. Historically, rubies from certain regions, such as Myanmar (Burma) and Mozambique, have been renowned for their exceptional pink hues. Pink rubies from these sources are often considered more valuable due to their scarcity and distinct color characteristics.

Supply and Demand:

The availability of pink rubies in the market is a crucial factor affecting their rarity and price. If the supply is limited or the demand is high, the rarity and value of pink rubies increase. Changes in mining conditions, political situations, or trade restrictions can impact the availability of pink rubies and influence their rarity.

Preserving the Rarity of Rubies

Preserving the rarity of rubies is crucial to maintain their value and ensure their continued appreciation. Responsible sourcing, ethical mining practices, and proper gemstone certification play important roles in safeguarding the rarity and integrity of rubies. Awareness of sustainable and ethical practices within the gemstone industry helps preserve the natural resources and environments where these rare gemstones are found.


The rarest types of rubies, such as Burmese “Pigeon’s Blood” rubies, Star Rubies, Alexandrite-like color change rubies, trapiche rubies, and pink rubies, capture the imagination and fascination of gemstone enthusiasts. These extraordinary gemstones stand out for their exceptional characteristics, scarcity, and unique properties. The rarity of these rubies contributes to their significant market value and their enduring allure among collectors and connoisseurs. By understanding the factors that influence rarity and appreciating the unique qualities of these exceptional gemstones, we can gain a deeper appreciation for the world of rubies and the rare treasures they hold.
