How to tell if a ruby is real? This is a question that has been asked throughout the ages, and there are many ways to determine its authenticity. In this guide, we will explore a few of the most popular methods used by experts to tell synthetic gems from real rubies.



STEP ONE: CHECK THE RUBY'S HARDNESS


As mentioned above, natural rubies are highly resistant to scratches, ranking a firm 9 on the Mohs scale of Hardness. Real rubies rank second in durability only to diamond and moissanite gems because a diamond ranks a 10 on the Mohs scale, while moissanite ranks a 9.25. This means that only a diamond (or an object with a hardness greater than 9) can scratch real rubies. This is the same for all gems on the Mohls Scale of Hardness. For example, a material such as glass (a common material in faux rubies) is a mere 5.5 on the hardness scale, so it can only scratch stones with a 5.0 hardness ranking or below.



THE RUBY SCRATCH TEST


This is how the ruby scratch test works. If you are able to scratch the surface of the ruby in question with your nails or any other sharp instrument that is not a diamond or moissanite, then you know it is a fake ruby gem. Only a gemstone with a higher hardness rating on the Mohs scale can scratch a real ruby gemstone.



THE RUB TEST:


In this method, you are looking to see if your ruby leaves behind a color streak. Use the ruby in question to scratch a hard, smooth surface, such as a piece of glass. If a streak of red color is left behind on the hard surface, then it is clear that you have a fake ruby on your hands.


A real ruby gem will never leave color in that way. The only issue with this technique is that you cannot be sure that the ruby is real if it doesn't leave a trace of color. However, you can only be certain that it is a fake ruby if it does.



COMMON RUBY IMITATIONS


Tourmaline: Tourmaline stones are crystal silicates (hardness is rated 7.0-7.5 on the Mohs scale). The pinkish-red variety of this stone is frequently marketed as other gemstones, including genuine rubies, although it is considerably softer.


Garnet: This is yet another variety of the same element, the mineral silicate. Garnet gems come in various hues, but unscrupulous gem dealers often market the red variety of this stone as genuine rubies.


Glass: Most fake rubies on the market consist of red-colored glass. These synthetic rubies are affordable but aren't exceptionally long-lasting. Additionally, genuine ruby stones typically have a higher refractive index than glass, meaning they sparkle and shine more than one-dimensional red glass.


Composite Rubies: These are natural rubies with red-colored glass fused into it. Mixing these two materials creates a larger, fake stone at a lower price point than natural ruby gemstones.


The disadvantage of composite rubies is that these stones contain glass and, thus, are easily fractured and harmed by chemicals in housekeeping supplies.



RUBY VS. GARNET


Garnet: Real rubies are relatively more flawed with inclusions than garnets, which are usually clearer. Real rubies are also a deeper and more distinct dark red, whereas garnet stones tend to be lighter and much paler. And finally, garnet (like tourmaline) is softer than natural rubies, with a Mohs Scale rating is 6.5 to 7.5.



STEP 2: CHECK THE RUBY'S COLOR



THE RICH COLOR TEST:


The color of your ruby stone is one of the best factors to look at first. An authentic ruby gemstone has a deep, rich hue. A ruby-red color that is so vivid that it looks bright, while fake rubies often appear pale and dull, as if there is no substance.



SPOTLIGHT RED:


Use the "stoplight red" as a guide, but do not expect to find a real ruby that is that bright. If you do, then the "natural ruby" is likely fake. However, an authentic ruby gemstone is more like a bright traffic light than a faux, dull stone.



DARK RED:


If a gem is more of a dark shade, it is probably a garnet instead of an actual ruby. Garnets are a common substitute for real rubies



THE GLASS TEST


Artificial rubies commonly consist of glass. To determine if you have an artificial ruby, compare it to similar-tinted glass. No genuine ruby will ever be identical to the color or tint of a piece of glass.



STEP 3: FEEL THE RUBY'S WEIGHT


Fake rubies are often less dense than real ones. To tell if a ruby is real, you must weigh the questionable stone and compare the weight to a similar-sized natural ruby. A fake stone will be lighter in weight than a real ruby.



STEP 4: A REAL RUBY IS PRICEY


The best indicator that you have a real ruby gem is its rarity. Most rubies on the market are synthetic rubies made in laboratories, so genuine rubies will always be rarer and more valuable. If the price of ruby gem is too low, there's a good chance it is a fake ruby - or a very low-quality one.


In general, a natural ruby is very costly. In contrast, a lab-created ruby is about 20% less expensive than a natural ruby, while a synthetic ruby can be up to 90% cheaper.


In terms of size, it is tough to find a natural ruby in a larger size. However, the stones that are the real deal and come in larger carats are extremely rare & expensive. If a ruby is quite large, there is a high probability that it is a synthetic ruby.



STEP 5: INSPECT THE RUBY'S CLARITY


Buy a ten-power (10x) jeweler's loupe online and inspect your "ruby" under high magnification. You will be able to detect tiny flaws on the surface of a natural ruby under a microscope in a process called spectroscopy. These flaws usually aren't visible to the naked eye.


These flaws are 'inclusions.' Natural ruby forms as a mineral deep in the earth; thus, a genuine ruby will always have flaws - sometimes a black spot, a line, or inclusions from foreign minerals.

In addition, a real ruby usually has consistent clarity; thus, your stone is likely not a real ruby if the clarity is not consistent throughout.



STEP 6: EXAMINE THE CUT RELATIVE TO ITS SIZE


Most real rubies over ½ carat in size are usually cut into fancy shapes, such as a pear or cushion shape. Thus, if you have a larger carat-size ruby in a round shape, it may be a false ruby.


 

STEP 7: NATURAL RUBIES COME WITH CERTIFICATION


If you're looking for natural rubies, be sure to check the certification. All reputable dealers will offer a certificate of authenticity with each ruby purchase. This document should include information on the 4 Cs of each ruby: carat weight, color, clarity, and cut. The certificate will also state whether a ruby is a treated or a non-treated stone. This is important because a non-treated ruby stone is more valuable than a treated one.


This last technique is the only foolproof way to check a natural ruby's authenticity. If the jeweler does not offer this documentation, the gemstone in question is likely a false ruby. When examining a potential ruby purchase, don't hesitate to ask questions. A reputable jeweler will be happy to answer them. And if you're still unsure, consult a gemologist or another expert before making your purchase.



WRAPPING UP


Now that you know how to tell if a ruby is real, it's up to you to make the final decision. If you're still not sure, ask a professional jeweler for their opinion. With a little knowledge and effort, you can be confident in your purchase. Thanks for reading!
