Rubies, with their mesmerizing red hues, have long been cherished as one of the most valuable gemstones in the world. But not all rubies are created equal. To truly appreciate the beauty and rarity of these gemstones, it’s essential to understand the various types of rubies that exist. In this comprehensive article, we will delve into the world of rubies, exploring their origins, characteristics, and the factors that differentiate one type of ruby from another.
I. Natural vs. Synthetic Rubies
The journey to understanding the different types of rubies begins with a fundamental distinction: natural versus synthetic. Natural rubies, formed deep within the Earth over millions of years, are the most sought-after and valuable. In contrast, synthetic rubies, also known as lab-grown or man-made rubies, are created in controlled environments. The keyword “what are the different types of rubies” underscores the significance of this division, as it sets the stage for further exploration.
Natural Rubies: A Gift from the Earth
Burmese Rubies: Renowned for their vivid, pigeon’s blood red color, Burmese rubies are considered some of the finest natural rubies in the world. These gemstones are typically characterized by their intense red hue with a slight bluish undertone, making them highly desirable among collectors and enthusiasts.
Thai Rubies: Thailand, too, has its own unique variety of rubies. Thai rubies are often lighter in color compared to Burmese rubies, with a warmer, reddish-pink tone. While they may not be as valuable as Burmese rubies, they still possess a captivating beauty that appeals to many.
Mozambique Rubies: Mozambique, a relatively recent player in the world of ruby mining, has gained recognition for its vibrant red rubies. These gems are often considered more affordable alternatives to their Burmese counterparts while maintaining remarkable color saturation.
African Rubies: Africa is a continent rich in gemstone resources, and it’s no surprise that it is also home to ruby deposits. African rubies can vary in color and quality, but they are known for their distinctive characteristics, often displaying rich reds and deep purples.
Star Rubies: Some natural rubies, irrespective of their origin, exhibit a remarkable optical phenomenon called asterism. Star rubies are characterized by a captivating star-like pattern on their surface, which is created by the presence of needle-like inclusions. The star effect, typically with six rays, is highly prized by collectors.
Synthetic Rubies: Crafting Perfection in the Lab
Flame Fusion Rubies: These synthetic rubies are created using the flame fusion method, which involves melting aluminum oxide (corundum) with specific chemical additives to mimic the natural growth of rubies. While they can closely resemble natural rubies in appearance, they lack the distinctive characteristics that define natural rubies.
Hydrothermal Rubies: Hydrothermal rubies are grown in high-pressure, high-temperature environments, closely replicating the geological conditions in which natural rubies form. They can possess excellent color and clarity, making them a preferred choice for jewelry manufacturers.
Verneuil Process Rubies: Named after its inventor Auguste Verneuil, this method involves melting powdered alumina and feeding it through a flame. As the material cools and solidifies, it forms a crystal that can be cut and faceted like natural rubies. These synthetic rubies are often used as affordable alternatives for jewelry.
II. Distinguishing Characteristics of Rubies
Once you grasp the difference between natural and synthetic rubies, it’s important to delve into the distinguishing characteristics that define the various types of natural rubies.
Color: The Heart of the Ruby
The color of a ruby is often referred to as its “heart.” It’s the primary factor that determines a ruby’s value and appeal.
Pigeon’s Blood Red: This term is used to describe the most coveted color in rubies. It refers to a pure, intense red with a slight bluish undertone, reminiscent of the color of freshly spilled pigeon’s blood. Burmese rubies are famous for exhibiting this extraordinary color.
Ruby Red: While not as intense as pigeon’s blood red, ruby red is still a vibrant and sought-after color. Thai rubies are often known for their ruby red color, which has a warm and inviting appearance.
Pinkish-Red: Some rubies, especially those from Mozambique and Africa, exhibit a pinkish-red color. These rubies are unique and captivating in their own right, offering a softer, more romantic hue.
Star Ruby Red: Star rubies, with their unique asterism, often display a deep red color with a mesmerizing star-like pattern on their surface. The presence of this optical effect enhances their allure.
Clarity: The Window to the Soul
Clarity in rubies refers to the absence of internal and external imperfections. While it’s rare to find a flawless ruby, high-quality rubies have minimal inclusions.
Eye-Clean: Rubies with excellent clarity are often described as “eye-clean,” meaning that any inclusions or imperfections are not visible to the naked eye. Such rubies are highly prized for their transparency and brilliance.
Visible Inclusions: Rubies with visible inclusions may have internal flaws or surface blemishes that are noticeable without magnification. While these rubies may be more affordable, their value is significantly lower compared to eye-clean rubies.
Star Inclusions: In the case of star rubies, the presence of needle-like inclusions that create the star-like optical effect is actually desirable. These inclusions add to the character and uniqueness of the gem.
Cut: Shaping the Ruby’s Brilliance
The cut of a ruby plays a crucial role in determining its overall beauty. A well-cut ruby reflects light in a way that showcases its color and brilliance.
Round Cut: Round-cut rubies are a classic choice, known for their symmetry and ability to reflect light beautifully. They are a popular choice for various types of jewelry, including rings and pendants.
Oval Cut: Oval-cut rubies have an elongated, elegant shape that can make fingers appear longer when set in a ring. They offer a unique alternative to the traditional round cut.
Emerald Cut: The emerald cut, with its step-cut facets, is known for its geometric and bold appearance. While not as common for rubies, it can create a distinctive and elegant look.
Heart Shape: Rubies cut in the shape of a heart are often chosen for romantic and sentimental jewelry pieces, such as engagement rings.
Cabochon Cut: This style of cut is commonly used for star rubies, as it enhances the star-like effect on the surface of the gem. It features a smooth, rounded, and polished surface without facets.
Carat Weight: Sizing Up the Ruby
The carat weight of a ruby is a measure of its size. While a larger ruby can be visually striking, the value of a ruby isn’t solely determined by its carat weight. Factors like color, clarity, and cut play equally significant roles in a ruby’s worth.
Larger Rubies: Rubies that weigh several carats or more are relatively rare and can command high prices, especially if they exhibit excellent color, clarity, and cut.
Smaller Rubies: Smaller rubies, while more common, can still be exquisite and are often used in jewelry settings that require more delicacy and subtlety.
III. Geographic Variations in Natural Rubies
Beyond the general categories of natural rubies, the geographical origin of a ruby can also influence its value and unique characteristics. The keyword “what are the different types of rubies” emphasizes the diversity of natural rubies available based on their origins.

Rubies from Thailand, while not as intensely red as Burmese rubies, possess their own charm. They often display a warm, reddish-pink tone, which is distinct from the cooler, bluish undertones of Burmese rubies.
Mozambique Rubies: Vibrant and Affordable
Mozambique, a relatively recent entrant in the world of ruby mining, has gained recognition for its vibrant red rubies. These gems are often considered more affordable alternatives to their Burmese counterparts while maintaining remarkable color saturation.
African Rubies: The Continent’s Riches
Africa is known for its abundant natural resources, and rubies are no exception. African rubies can vary in color and quality, but they are known for their distinctive characteristics, often displaying rich reds and deep purples.
Star Rubies: A Celestial Touch
Star rubies can come from various regions but share the unique feature of asterism, which creates a star-like pattern on the gem’s surface. The presence of this optical effect sets star rubies apart and makes them highly sought after by collectors.
IV. Treatments and Enhancements
To understand the different types of rubies fully, it’s essential to consider the various treatments and enhancements that may be applied to these gemstones. Some treatments are intended to improve the gem’s appearance, while others may have ethical or environmental implications.
Heat Treatment: Heat treatment is a common practice in the ruby industry. It involves heating the gemstone to high temperatures to improve its color and clarity. Many rubies on the market have undergone this treatment to enhance their natural beauty.
Lead Glass Filling: This treatment is used to fill fractures and cavities in rubies with lead glass, improving their appearance. While it can make a lower-quality ruby look more attractive, it’s crucial to disclose this treatment to buyers for ethical reasons.
Diffusion Treatment: Diffusion treatment introduces specific elements, like beryllium, into the ruby’s surface to alter its color. While this can create visually striking rubies, it’s essential for consumers to be aware of any treatments when purchasing gemstones.
