Real Ruby? Easy Tests To Spot A Fake Gemstone

Hey gem enthusiasts! Ever wondered if that stunning ruby you've got your eye on is the real deal? Ruby, with its fiery red hue, is one of the most coveted gemstones in the world. But, like any precious gem, there are imitations and treatments out there. So, how do you tell if a ruby is real? Don't worry, guys, I'm here to walk you through some simple tests and tips to help you distinguish a genuine ruby from a fake. Let's dive in!

Understanding the Allure of Rubies

Before we get into identifying a real ruby, let's quickly appreciate what makes these gems so special. Rubies are a variety of the mineral corundum, the same mineral family as sapphires. What gives a ruby its characteristic red color? It's the presence of chromium! The intensity of the red can vary, with the most prized rubies displaying a vibrant, rich red often referred to as "pigeon's blood." Throughout history, rubies have been associated with passion, courage, and prosperity. They've adorned the crowns of royalty and been treasured as symbols of love and power. This rich history and captivating color contribute to the ruby's enduring appeal. But with this allure comes the need to be discerning. The market for rubies includes both natural and synthetic stones, as well as various treatments to enhance color and clarity. Understanding these factors is crucial to making an informed purchase and ensuring you're getting what you pay for. So, let's equip ourselves with the knowledge to confidently identify a real ruby!

Visual Inspection: The First Line of Defense

Okay, so you've got a ruby in your hands. The first thing you'll want to do is give it a good, thorough look. This visual inspection is your first line of defense against fakes. What are we looking for? Well, color is a big one. Real rubies have a deep, vivid red color. But remember, the shade can vary depending on the origin and quality of the stone. Some might lean towards a more purplish-red, while others have a more orangey-red hue. The key is to look for a rich, intense color. Uniformity of color can also be a clue. Natural rubies often have slight variations in color zoning, meaning the color might be a bit unevenly distributed throughout the stone. This is because of the way the gem formed naturally over time. A perfectly uniform color might be a sign of a synthetic ruby, which is created in a lab under controlled conditions. However, some natural rubies can also exhibit even color distribution, so this isn't a definitive test on its own. Next, check for inclusions. Inclusions are tiny imperfections within the gem, like small crystals or needles. Most natural rubies have some inclusions. These are like the gem's fingerprints, telling a story about its formation. A ruby that looks absolutely flawless under magnification might be a synthetic. But again, clarity varies in natural rubies, and some high-quality natural rubies can have very few inclusions. We'll talk more about magnification and other tests later, but for now, just use your eyes and observe the color and clarity of the stone. Does it have a vibrant, natural-looking red? Are there any slight imperfections? These initial observations can give you valuable clues.

The Scratch Test: Hardness Matters

Now, let's talk about hardness, guys! This is a really important property when it comes to gemstones. Hardness refers to a gem's resistance to scratching. The Mohs Hardness Scale is used to measure this, with diamonds being the hardest at a 10 and talc being the softest at a 1. Rubies are a 9 on the Mohs scale, which means they're incredibly durable and resistant to scratching. This high hardness is one of the reasons why rubies are so prized for jewelry – they can withstand daily wear and tear. So, how can we use this to test if a ruby is real? Well, a scratch test can give us some valuable information. But it's crucial to do this test carefully and ethically! You should only perform a scratch test on a stone you own or with the explicit permission of the owner. And it's best to test an inconspicuous area of the gem, like the back of the stone. To perform the test, you'll need a known material of a certain hardness. For example, a piece of corundum (like a sapphire, which also has a hardness of 9) or a moissanite (which has a hardness of around 9.25). If your ruby can scratch the corundum, it's likely a ruby. If the corundum scratches the ruby, then your stone is likely a fake. It's important to note that this test isn't foolproof. Some materials, like synthetic corundum, can also have a hardness of 9. And remember, scratching a gem can damage it, so proceed with caution! If you're unsure, it's always best to consult a professional gemologist.

The Magnification Examination: Unveiling the Details

Alright, let's get up close and personal with our ruby! Using magnification is a fantastic way to really see the details of a gemstone and uncover clues about its authenticity. A jeweler's loupe, which is a small magnifying glass, is a great tool for this. You can find them online or at jewelry stores. With magnification, we're looking for several things. First, let's talk about inclusions again. As we mentioned earlier, most natural rubies have inclusions. Under magnification, you might see tiny crystals, needles, or even fluid-filled cavities within the gem. These inclusions are a natural part of the ruby's formation process and can be a good sign of authenticity. The type and pattern of inclusions can even help gemologists determine the origin of the ruby! Synthetic rubies, on the other hand, are grown in a lab under controlled conditions. This means they often have fewer inclusions, or the inclusions they do have look different from those found in natural rubies. For example, synthetic rubies might have curved growth lines or gas bubbles, which are telltale signs of lab-created gems. But it's not just about inclusions. Magnification can also reveal surface features. Natural rubies might have slight surface irregularities or wear marks, which are a result of their journey from the earth to your hands. Synthetic rubies often have a more pristine surface. Another thing to look for under magnification is the quality of the polish. A well-polished ruby will have a smooth, lustrous surface. An uneven or poorly polished surface could be a sign of a lower-quality stone or even a fake. So, grab a loupe, guys, and take a closer look! You might be surprised at what you discover.

The Light Test: Is It Glowing Red?

Let's play with some light, guys! The light test can be a really cool and informative way to assess a ruby. Rubies exhibit a phenomenon called fluorescence, which means they glow when exposed to ultraviolet (UV) light. This glow is due to the presence of chromium, the same element that gives rubies their red color. Now, not all rubies fluoresce equally. The intensity of the fluorescence can vary depending on the amount of chromium present and other factors. But, in general, a real ruby will often exhibit a strong red fluorescence under UV light. This red glow can be quite striking and is a good indication that you're dealing with a genuine ruby. So, how do you perform this test? You'll need a UV light source, which you can find online or at some hardware stores. A shortwave UV light is generally recommended for testing rubies. In a darkened room, shine the UV light on the ruby and observe its reaction. Does it glow a vibrant red? If so, that's a positive sign. However, it's important to note that some synthetic rubies can also fluoresce, so this test isn't foolproof on its own. Also, some treatments can affect a ruby's fluorescence. For example, heat treatment, which is commonly used to enhance the color and clarity of rubies, can sometimes reduce or eliminate fluorescence. So, while the light test can be a helpful tool, it's best used in conjunction with other tests to get a complete picture.

The Specific Gravity Test: A Deeper Dive

Okay, guys, let's get a little more technical! Specific gravity is a term that might sound intimidating, but it's actually a pretty simple concept. It's the ratio of the density of a substance to the density of water. In other words, it tells us how heavy a substance is compared to water. Rubies have a specific gravity of around 3.97 to 4.05. This means they're about four times as dense as water. This relatively high density is a characteristic property of rubies and can be used to help identify them. So, how do we measure specific gravity? Well, it involves a little bit of math and some specialized equipment. You'll need a gemological scale, which is a highly accurate scale designed for weighing gemstones, and a container of water. First, you weigh the ruby in air. This gives you its weight in grams. Then, you weigh the ruby while it's submerged in water. This is a bit trickier, but you can use a special setup with the scale and a container of water to do this. The difference between the weight in air and the weight in water is the loss of weight in water. Now, here's the math: Specific Gravity = Weight in Air / (Weight in Air - Weight in Water) So, you plug in the numbers you got from your measurements, do the calculation, and you'll get the specific gravity of your ruby. If the result falls within the range of 3.97 to 4.05, that's a good indication that it's a ruby. However, this test isn't foolproof either. Some other gemstones and synthetics can have similar specific gravities. So, like the other tests, it's best used in combination with other methods.

When to Call in the Experts: Gemological Certification

Alright, guys, we've covered a lot of ground! We've talked about visual inspection, scratch tests, magnification, light tests, and even specific gravity. These are all valuable tools for identifying a real ruby. But let's be honest, gem identification can be tricky! There are many factors to consider, and some fakes are very convincing. So, what do you do when you're still unsure? That's when it's time to call in the experts! A gemologist is a trained professional who specializes in identifying and grading gemstones. They have the knowledge, experience, and equipment to accurately assess a ruby and determine its authenticity, origin, and any treatments it may have undergone. Gemologists use a variety of sophisticated instruments and techniques, including microscopes, refractometers, and spectrometers, to analyze gemstones. One of the best ways to ensure you're getting a real ruby is to purchase a gem with a gemological certificate. These certificates are issued by reputable gemological laboratories, such as the Gemological Institute of America (GIA) or the American Gem Trade Association (AGTA). A gemological certificate will provide a detailed description of the ruby, including its color, clarity, cut, carat weight, and any treatments detected. It will also state whether the ruby is natural or synthetic. Having a gemological certificate provides peace of mind and can be especially important for valuable rubies. So, if you're making a significant investment in a ruby, it's definitely worth the cost to get it certified. Think of it as an insurance policy for your precious gem!
