Rubies are one of the most sought-after gemstones in the world. Their rich color and stunning beauty make them popular in jewelry. However, the market is flooded with both natural and synthetic rubies. It is essential to know how to identify a real ruby. This article will guide you through the various methods and characteristics to help you determine the authenticity of a ruby.
Understanding Rubies
Before diving into the identification process, it is essential to understand what rubies are. Rubies are a variety of the mineral corundum. They are composed primarily of aluminum oxide and have traces of chromium, which gives them their vibrant red color. Rubies are highly valued for their color, clarity, size, and cut.
Natural rubies are rare and more valuable than synthetic ones. Synthetic rubies are created in laboratories and can often be mistaken for real rubies. Understanding the differences between these two types is crucial for identifying a real ruby.
Checking the Color
The first step in identifying a real ruby is to examine its color. Genuine rubies typically exhibit a vibrant red color. This red can range from pinkish to purplish hues. However, the most prized rubies are a deep, rich red known as “pigeon’s blood.”
When evaluating the color, consider the following points:
Evenness: A real ruby should have an even color throughout. Look for any patches or uneven coloring.
Intensity: The color should be intense and vivid. Pale or dull colors may indicate a synthetic ruby or a lower-quality stone.
Tone: A genuine ruby has a medium to dark tone. Very light rubies may not be real.
Inspecting Clarity
Clarity is another important factor in determining if a ruby is real. Natural rubies often have inclusions, which are internal flaws. These inclusions can be tiny crystals, gas bubbles, or other minerals. The presence of these inclusions is common in natural rubies.
When assessing clarity, consider these aspects:
Inclusions: Use a jeweler’s loupe or a magnifying glass to look for inclusions. If you see tiny flaws, it is likely a natural ruby. Synthetic rubies often appear flawless.
Bubbles: Look for small gas bubbles, which can indicate a synthetic ruby. Natural rubies typically do not have these bubbles.
Nature of Inclusions: The inclusions in a natural ruby often have unique patterns. Synthetic rubies tend to have straight and organized inclusions.
Evaluating Cut and Shape
The cut and shape of a ruby can also provide clues to its authenticity. Real rubies can be cut in various shapes, including oval, round, cushion, and pear. The quality of the cut affects how light interacts with the stone, influencing its brilliance and sparkle.
When examining the cut and shape, look for:
Symmetry: A well-cut ruby will have symmetrical facets. An uneven cut may indicate a lower-quality stone.
Proportions: The proportions of the ruby should be visually appealing. A poorly proportioned stone can suggest a synthetic ruby.
Facets: Examine the facets for sharpness and clarity. Synthetic stones may have a glass-like appearance due to their perfect cuts.
Performing the Scratch Test
The scratch test is a simple way to check if a ruby is real. Rubies have a hardness of 9 on the Mohs scale. This makes them very resistant to scratching. You can perform this test at home but be careful to avoid damaging the stone.
To conduct the scratch test:
Use a Hard Material: Find a material that is softer than a ruby, such as glass or a piece of ceramic.
Scratch the Surface: Lightly scratch the ruby against the surface of the glass or ceramic.
Observe: If the ruby is real, it should not show any scratches or marks. If it scratches easily, it may not be genuine.
Utilizing the Water Test
The water test is another simple method to help determine if a ruby is real. This test examines the stone’s density. Real rubies are denser than many fake stones, which can affect how they behave in water.
To perform the water test:
Fill a Glass with Water: Use a clear glass and fill it with water.
Drop the Ruby: Gently drop the ruby into the glass of water.
Observe the Behavior: A real ruby will sink quickly to the bottom due to its density. If it floats or hovers, it may be a fake.
Using a UV Light Test
Rubies exhibit fluorescence under ultraviolet (UV) light. This means they can glow brightly when exposed to a UV light source. This property is especially common in natural rubies.
To conduct the UV light test:
Obtain a UV Light: Use a UV flashlight or black light.
Expose the Ruby: Shine the UV light on the ruby in a dark room.
Observe the Glow: A genuine ruby will often fluoresce a bright red or pink color. If the ruby does not glow or glows differently, it may be synthetic.
Consulting a Gemologist
If you are still unsure about the authenticity of your ruby, consulting a professional gemologist is a wise choice. A gemologist has the expertise and tools to accurately assess gemstones. They can provide a detailed report on the stone’s characteristics and authenticity.
When visiting a gemologist, consider asking about:
Certification: Ask if the gemologist can provide certification for the ruby. A certified gemologist can offer valuable insights and guarantee the stone’s authenticity.
Advanced Testing: A gemologist may conduct advanced tests that are not possible at home. These tests can include refractive index measurements and specific gravity tests.

Conclusion
Identifying a real ruby requires careful examination and understanding of the gemstone’s characteristics. By evaluating the color, clarity, cut, and using various tests, you can determine if a ruby is genuine. Remember that consulting a professional gemologist is always a good option if you are unsure.
Knowing how to identify a real ruby will not only protect your investment but also enhance your appreciation of this stunning gemstone. Whether for personal enjoyment or investment purposes, understanding rubies is essential for any jewelry lover. Always remember to conduct thorough tests and seek professional guidance when necessary. This way, you can enjoy your beautiful rubies with confidence.
