How to tell if a ruby is real
Ruby is known for its exquisite beauty and deep red color. However, distinguishing between a genuine ruby and a synthetic or imitation one can be challenging for the untrained eye. To avoid being deceived and to ensure your ruby is the real deal, it is essential to familiarize yourself with certain key characteristics and effective identification tools.
One of the first things to look for when determining if a ruby is genuine is its hardness. Real rubies are one of the hardest gemstones, ranking 9.0 on the Mohs scale. This means they are very resistant to scratching and can only be scratched by a diamond. Therefore, if a stone can be easily scratched by other materials, it is likely an imitation or a different gemstone altogether.
In addition to its hardness, a genuine ruby also possesses exceptional brilliance and luster. Real rubies have a vibrant shine that reflects light in a captivating manner. When examining a ruby, hold it up to a light source and observe the way it glimmers and sparkles. A genuine ruby will exhibit unparalleled brilliance, characterized by a bright and vivid color that seems to glow from within.
Another characteristic to pay attention to is the presence of any imperfections or inclusions. Real rubies often contain natural imperfections, such as tiny discolorations or internal fractures, known as “birthmarks” or “silk.” These imperfections are a natural part of the gemstone and actually enhance its authenticity. Conversely, synthetic rubies are usually flawless and lack any noticeable inclusions. Therefore, if a ruby appears to be too perfect and flawless, it is likely a lab-grown synthetic or an imitation stone.
How to Authenticate a Ruby Gemstone: A Complete Guide
A ruby gemstone is one of the most valuable and sought-after gemstones in the world. However, due to its high value, there is always a risk of encountering counterfeit or synthetic rubies. To ensure that you are purchasing a genuine ruby gemstone, it is essential to authenticate it. Here is a complete guide on how to authenticate a ruby gemstone:
1. Color and Clarity
The color of a ruby is one of the primary indicators of its authenticity. Genuine rubies typically exhibit a deep red color, often referred to as “pigeon’s blood” red. Synthetic or fake rubies may have a more vibrant or purplish hue. Additionally, natural rubies often have slight imperfections called inclusions, which can help determine their authenticity.
2. Hardness
Rubies are one of the hardest gemstones, second only to diamonds. This hardness is measured on the Mohs scale, with rubies having a ranking of 9. Fake rubies or imitations made from materials like glass or synthetic materials will have a lower hardness.
3. Refraction and Reflectivity
Genuine rubies refract and reflect light in a specific way. They have a high refractive index, meaning that light passing through them can be bent and dispersed. If you shine a light through a ruby and see the light bending or dispersing, it is likely genuine. Synthetic rubies may have a lower refractive index, resulting in less bending or dispersion.
4. Heat Treatment
Many rubies undergo heat treatment to enhance their color and clarity. This process is common and accepted within the gemstone industry. However, if a ruby is significantly more vibrant or lacks any imperfections, it may indicate that it has been artificially treated. Always inquire about any treatments the ruby may have undergone before making a purchase.
It is important to note that while these steps can help indicate the authenticity of a ruby gemstone, they are not foolproof. To be certain, it is recommended to seek the assistance of a professional gemologist or purchase from reputable sources to ensure you are getting a genuine ruby.
Remember: With proper knowledge and careful examination, you can authenticate a ruby gemstone and make a confident purchase.
Identifying Genuine Rubies: Physical Characteristics to Look For
When determining if a ruby is real or not, there are several physical characteristics to observe. By examining these factors, you can make a more informed decision about the authenticity of a ruby. Here are some key features to look for:
Colour
Rubies are known for their vibrant, deep red color. Genuine rubies will typically showcase a rich and intense hue. Be wary of rubies that appear too light or have secondary colors present, as these may indicate a synthetic or treated stone.
Clarity
Genuine rubies often have some degree of natural inclusions, which are internal features formed during their formation. These inclusions can be seen under magnification and are a reliable indicator of authenticity. However, be cautious of rubies that are completely transparent without any internal flaws, as this could be a sign of a lab-created gem.
On the other hand, if a ruby has numerous or large blemishes that affect its transparency and brilliance, it may be a lower-quality stone.
Cut
The cut of a ruby refers to its shape and faceting. Genuine rubies are commonly cut into faceted shapes to enhance their brilliance. Look for precise cuts with clean and well-defined facets, as these are indicative of a real ruby.
Hardness
Rubies are one of the hardest gemstones, with a Mohs scale rating of 9. This means they are resistant to scratches and can withstand daily wear. To test the hardness of a ruby, see if it can scratch materials like glass or quartz. A genuine ruby will leave a noticeable mark.
When in doubt, it is advisable to consult a professional gemologist or jeweler who can evaluate the ruby’s physical characteristics further and provide an expert opinion.
- Colour
- Clarity
- Cut
- Hardness
By paying attention to these physical characteristics, you can become better equipped at identifying genuine rubies and avoid falling for imitations or synthetic stones.
Spotting Common Fake Ruby Gemstone Treatments
While it is always best to have a professional gemologist authenticate a ruby, there are some signs that can help you spot common fake ruby gemstone treatments. These treatments are often used to enhance the appearance or value of lower-quality rubies. Here are a few things to look for:
| Treatment | Description | How to spot it |
|---|---|---|
| Fillings | Rubies may have fissures, cracks, or cavities filled with glass or other substances to improve clarity and color. | Look for bubbles, uneven coloring, or flashes of color in the fissures. Rubies with perfect transparency are likely to be natural. |
| Heat treatment | Rubies are often heat-treated to enhance their color and clarity. | Look for color zoning or uneven color distribution, as heat treatments can cause slight changes in color intensity. Also, natural inclusions in a heat-treated ruby will have rounded edges. |
| Dyeing | Rubies can be treated with dyes to improve their color. | Check for uneven color distribution or color that fades over time. Scratching the surface of the stone with a pin may reveal the true color underneath if it has been dyed. |
| Diffusion treatment | Chemicals can be applied to the surface of a ruby and then heated to create color-changing effects or star-like patterns. | Look for color concentration on the surface or unnatural color zoning. Natural rubies typically have more uniform color distribution. |
| Synthetic rubies | Rubies can be created in a lab and may have the same physical and chemical properties as natural rubies. | Look for significant cost differences, perfect clarity, or extremely large-sized rubies, as these can be indications of synthetic stones. Check for any accompanying certificates or documentation. |
If you come across a ruby that exhibits any of these signs, it is advisable to consult with a professional gemologist or jewelry expert to get a proper evaluation and authentication.
Conducting Simple Home Tests to Determine Authenticity
When determining the authenticity of a ruby, there are several simple tests that can be conducted at home to help you make an informed decision. While these tests are not foolproof, they can provide you with some insight into the genuineness of your ruby. Here are a few tests you can try:
- Scratch Test: Rub the ruby against a hard, smooth surface such as glass. If the ruby leaves a scratch on the glass, it is most likely genuine. However, if the ruby gets scratched or shows signs of damage, it may be a synthetic or imitation gemstone.
- Transparency Test: Hold the ruby up to a light source and examine its transparency. Genuine rubies are generally transparent or slightly translucent, allowing some light to pass through. If the ruby appears cloudy or opaque, it may be a synthetic gemstone.
- Magnet Test: Place a small magnet near the ruby and observe its behavior. Natural rubies are not magnetic, so if the stone is attracted to the magnet, it is likely a fake. Keep in mind that certain rubies with iron content may exhibit a very weak magnetic response.
- Weight Test: If you have access to a precision scale, you can measure the weight of the ruby. Natural rubies are generally heavier than synthetic or imitation gemstones. While this test alone cannot confirm authenticity, a significantly lighter weight may indicate a fake ruby.
Please note that these home tests are not definitive evidence of a ruby’s authenticity. For a conclusive determination, it is always recommended to consult with a professional gemologist or jeweler who can use specialized equipment and techniques to accurately assess the gemstone.
The Role of Certification and Grading in Evaluating Ruby Gemstones
When it comes to evaluating the authenticity and quality of a ruby gemstone, certification and grading play a crucial role. These processes involve thorough examination and analysis of the gemstone’s characteristics by certified gemologists or reputable gemological laboratories.
The certification process verifies that a ruby is indeed a natural gemstone and not an imitation or synthetic material. It also provides information on the ruby’s country of origin, dimensions, weight, and any enhancements or treatments that have been applied. Certification ensures transparency and enables buyers to make informed decisions based on accurate information about the gemstone.
| Certification | Grading |
|---|---|
| Certification involves the examination of the ruby’s physical and optical properties to determine its authenticity and origin. The gemstone is evaluated for clarity, color, cut, and carat weight. | Grading involves a detailed assessment of a ruby’s overall quality and beauty. The gemstone is graded on the basis of its color intensity, hue, saturation, transparency, and presence of any inclusions or flaws. |
It is important to note that certification and grading are commonly performed following international standards established by leading gemological institutions, such as the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). The certificates and reports issued by these institutions are widely recognized and trusted within the industry.
When purchasing a ruby gemstone, it is highly recommended to acquire a certified and graded stone from a reputable dealer or source. This ensures that you are receiving a genuine ruby of high quality and value. Additionally, having a certified and graded ruby can also enhance its resale potential in the future.
In conclusion, certification and grading play a vital role in evaluating ruby gemstones. They provide valuable information about the gemstone’s authenticity, origin, and quality. By obtaining a certified and graded ruby, you can have confidence in your purchase and ensure that you are acquiring a genuine and valuable gemstone.
