How to Tell if a Ruby Is Real (Guide)

Welcome to our comprehensive guide on determining the authenticity of rubies. Rubies are renowned for their deep, vivid red color and are often associated with passion and love. As one of the hardest gemstones, they hold immense value and allure. However, it can be challenging to distinguish between natural, synthetic, and imitation rubies. In this guide, we will explore the key signs of real rubies and provide you with valuable insights on how to identify them.

Before delving into the specifics of determining the authenticity of rubies, let’s briefly understand the different types. Natural rubies are formed without any human intervention and are considered the most valuable. Synthetic rubies, on the other hand, are laboratory-created and possess the same physical and chemical properties as natural ones. Lastly, imitation rubies are made from alternative materials and are significantly less expensive than real rubies.

To ensure you can accurately identify if a ruby is real, we will discuss various factors to consider. These include examining the color, clarity, cut, hardness, weight, and conducting specific tests such as the scratch test, rub test, and heat test. While these methods can offer valuable insights, it’s always advisable to consult a professional gemologist for a definitive assessment.

Key Takeaways:

• Real rubies exhibit a deep, vibrant red color and are often described as “bright” or “glowy”.
• Imitation stones such as garnet, tourmaline, glass, and composite gems can be compared to rubies to determine authenticity.
• Scratch tests can help identify genuine rubies, as they are exceptionally hard and should not show any scratches.
• Rub tests can be conducted to check if a ruby leaves a red mark, indicating potential artificial coloring.
• Consulting a professional jeweler or gemologist is crucial for a thorough appraisal and certification of a ruby’s authenticity.

Color and Shine

One of the key factors in determining the authenticity of a ruby is its color. Real rubies have a deep, vibrant red color that is often described as “bright” or “glowy.” This rich red hue is what makes rubies highly sought after and prized. In contrast, fake rubies tend to have a dull appearance and lack the same brilliance as genuine rubies. The color of a ruby can vary from medium to dark tones, but if it appears excessively bright or neon-like, it may be a synthetic or imitation stone. It’s important to note that while rubies can have some imperfections, they should not be excessively bright or appear fake.

To further assess the authenticity of a ruby based on its color, it’s important to consider the consistency and evenness of the color throughout the stone. Real rubies will typically have a uniform color distribution, with the entire gemstone exhibiting the same vibrant red hue. Fake rubies, on the other hand, may have variations or inconsistencies in color, which can be a sign of their artificial nature. By closely examining the color and shine of a ruby, you can gain valuable insights into its authenticity.

By understanding the distinct color and shine characteristics of real rubies, you can make more informed decisions when assessing the authenticity of these precious gemstones. Remember, if you have any doubts about the legitimacy of a ruby, it is always best to consult with a professional gemologist or jeweler who can provide expert advice and evaluation.

Comparing to Imitation Stones

When determining the authenticity of a ruby, it is essential to compare it to imitation stones. There are several common imitation stones that are often used to mimic the appearance of rubies. By understanding the characteristics of these imitations, you can easily identify a genuine ruby.

Garnet

Garnets are frequently used as an imitation for rubies due to their similar red color. However, there are distinct differences between garnets and real rubies. Garnets are dull and dark-red silicate minerals, and they are much softer than rubies. When comparing a garnet to a ruby, you can examine their hardness and brilliance. Rubies are significantly harder than garnets and exhibit a vibrant red color with a distinct glow.

Tourmaline

Tourmaline is another gemstone that is sometimes used as an imitation for rubies. While tourmaline can have a reddish-pink color similar to rubies, it is important to note that it is softer than both rubies and garnets. By comparing the hardness of a tourmaline to that of a ruby, you can easily distinguish between the two. Rubies are one of the hardest gemstones, while tourmaline falls short in comparison.

Glass and Composite Gems

Red-colored glass imitations and composite gems are also commonly used as substitutes for rubies. Glass imitations are typically inexpensive and lack the durability and vibrancy of real rubies. Composite gems, on the other hand, are real rubies that have been fused with glass to increase their size and value. These imitations are often sold as “real” rubies, so it is crucial to exercise caution when purchasing. By closely examining the appearance and conducting additional tests, such as the scratch test and rub test, you can verify the authenticity of the ruby.

By familiarizing yourself with these imitation stones and understanding their distinguishing characteristics, you can confidently identify genuine rubies and make informed decisions when purchasing or evaluating ruby gemstones.

Conducting Scratch Tests

One of the most effective methods to determine the authenticity of a ruby is by conducting a scratch test. Genuine rubies are known for their exceptional hardness, ranking at 9 on the Mohs scale, making them highly resistant to scratches. To perform this test, you can use your fingernail or a coin to scratch the surface of the ruby gently.

If the stone shows any visible scratches, it is likely not a genuine ruby. However, it’s important to note that composite rubies, which are real rubies fused with glass, may exhibit some scratches due to the softer nature of the glass. If the scratches are deep and easily visible, it is an indication that the stone is not a genuine ruby.

The Durability of Real Rubies

Real rubies are renowned for their exceptional durability, making them highly resistant to scratches and damage. This is due to their high hardness and resilience. Synthetic rubies, on the other hand, may lack the same level of durability and can often be scratched more easily. By performing a scratch test, you can assess the durability of the ruby and determine its authenticity.

It’s important to note that while a scratch test can provide valuable insights, it should not be the sole determinant in identifying a genuine ruby. Other factors such as color, shine, clarity, and professional gemological assessment should also be taken into consideration for a comprehensive evaluation.

While scratch tests can provide valuable insights into the authenticity of rubies, it is essential to seek professional expertise from a gemologist or jeweler for a definitive assessment. They have the knowledge and tools to accurately evaluate the gemstone and provide valuable guidance.

Conducting Rub Tests

Another effective method for determining the authenticity of a ruby is by conducting a rub test. This simple test involves gently scratching the ruby against a hard, smooth surface such as a porcelain tile or clear glass. If the ruby leaves a red mark on the surface, it could suggest that the gem is artificially colored. This is a potential indicator that the stone is made from weaker materials and is not a genuine ruby. However, it is important to note that some genuine rubies may not leave a mark, so this test alone is not definitive.

It is essential to exercise caution when interpreting the results of a rub test. While a visible red mark may indicate an artificially colored gem, other factors such as the pressure applied during the test and the quality of the testing surface can also influence the outcome. Therefore, it is advisable to consider the rub test in conjunction with other evaluation methods to draw a more accurate conclusion.

While the rub test can provide some insights into the authenticity of a ruby, it is important to remember that it is not a foolproof method. To obtain a more comprehensive assessment, it is recommended to consult a professional gemologist or jeweler who can utilize advanced techniques and equipment for a thorough examination. These experts have the experience and knowledge to accurately identify genuine rubies and distinguish them from imitations.

Keep in mind that conducting a rub test requires caution and an understanding of its limitations. While it can offer valuable insights, it should be used in conjunction with other evaluation methods and in consultation with experts for a more accurate assessment of a ruby’s authenticity.

Understanding the Types of Fake Rubies

When it comes to identifying real rubies, it’s crucial to understand the various types of fake rubies that are commonly found in the market. By familiarizing yourself with these fake stones, such as garnets, tourmaline, glass, and composite rubies, you can better distinguish them from genuine rubies.

Garnets, which are dark-red silicate minerals, are much softer than rubies and have a dull appearance. Tourmaline, on the other hand, is a reddish-pink silicate mineral that is harder than garnet but still softer than ruby. These stones lack the vibrant red color and brilliance of genuine rubies.

Red-colored glass imitations are often sold as rubies but can be easily identified due to their lack of durability and vibrant color. These imitations are typically cheaper and do not possess the same physical and chemical properties as real rubies.

Composite rubies, also known as “assembled rubies,” are real rubies that have been fused with glass to increase their size and value. While they may look like genuine rubies at first glance, certain characteristics, such as air bubbles or a lack of natural flaws, can give them away as imitations.

By gaining a deeper understanding of these different types of fake rubies, you can confidently evaluate and distinguish genuine rubies from imitations. However, it’s worth noting that the most accurate assessment can be made by consulting a professional gemologist or jeweler.

Consulting a Professional Jeweler

Inspecting the Ruby with a Magnifier

When examining a ruby to determine its authenticity, one important tool to have is a 10-power magnifier or access to a standard microscope. By closely inspecting the stone under magnification, you can look for small, microscopic flaws or inclusions that are often indicative of a genuine ruby. Real rubies typically have natural imperfections, such as tiny crystals, color zoning, or tiny pits, which add to their uniqueness and value.

On the other hand, synthetic rubies are usually flawless and lack these natural flaws. So, by using a magnifier, you can spot the difference and make a more informed assessment of the ruby’s authenticity. However, it’s essential to be aware of the different types of flaws that can be present in natural rubies, such as scratches, pits, nicks, and crystal inclusions, as these can vary in appearance and affect the stone’s overall quality.

Remember, the magnifier is a useful tool to aid your evaluation, but it should be used in conjunction with other tests and observations to arrive at a more accurate conclusion regarding the ruby’s authenticity.

Understanding Different Types of Flaws in Rubies

Flaws in rubies, also known as inclusions, are natural characteristics that can provide valuable insights into a gemstone’s authenticity. Here are some common types of flaws to look out for:

• Scratches: These are visible marks on the surface of the ruby caused by wear or accidental contact with a hard object. Deep scratches can indicate that the stone is not a genuine ruby.
• Pits: Pits are small indentations on the surface of the ruby. They can occur naturally during the gem’s formation or as a result of wear and tear over time.
• Nicks: Nicks are small chips or notches along the edges of the ruby. They can occur when the stone comes into contact with a hard surface or during the cutting and shaping process.
• Crystals: Crystal inclusions are tiny mineral formations within the ruby. These natural formations can vary in size, shape, and color and are a testament to the gemstone’s authenticity.
• Color Zoning: Color zoning refers to uneven distribution of color within the ruby. Natural rubies often exhibit variations in color intensity, which can add to their beauty and value.

By familiarizing yourself with these various flaws, you can better evaluate a ruby’s authenticity and appreciate the unique characteristics that make each gemstone truly one-of-a-kind.

Evaluating the Ruby’s Cuts and Facets

When examining a ruby to determine its authenticity, it is essential to pay close attention to the cuts and facets of the gemstone. The way a ruby is cut can provide valuable insights into its quality and whether it is a genuine stone.

A well-cut ruby will have symmetrical facets that are evenly distributed throughout the gemstone. These symmetrical facets allow light to reflect and refract in a uniform manner, creating a beautiful sparkle and enhancing the overall beauty of the ruby. On the other hand, poorly cut rubies may have irregular or unevenly shaped facets, which can be an indication of a fake gem. These irregular cuts can affect the way light interacts with the stone, resulting in a diminished visual appeal.

It is important to note that while round-shaped rubies are common, larger rubies are often cut in complex shapes like pear or cushion to maximize their beauty and optical properties. However, if you come across round-shaped rubies in larger sizes, it may raise a red flag as natural rubies are typically cut to accentuate their brilliance and unique characteristics. Keep in mind that the consistency and quality of the cuts and facets can provide valuable clues about the authenticity of the ruby you are evaluating.

“The quality of the cuts and facets play a crucial role in determining the authenticity of a ruby. Genuine rubies will have symmetrical facets, reflect light evenly, and may be cut in complex shapes. On the other hand, fake rubies may have irregular cuts, compromised reflection, and round shapes in larger sizes.”
