Amethyst is a beautiful and popular gemstone known for its rich purple hue. It has captivated people for centuries, both for its stunning beauty and its historical significance. Whether you’re a jewelry lover, a collector, or someone interested in purchasing amethyst for the first time, it’s essential to know how to tell a real amethyst from a fake one. This article will walk you through everything you need to know about identifying genuine amethyst.
What Is Amethyst?
Amethyst is a variety of quartz that is prized for its vibrant purple color. Its color can range from light lavender to deep purple. The stone is primarily composed of silicon dioxide and contains traces of iron, which is responsible for its color. Amethyst has been used in jewelry for centuries and is considered the birthstone for February.
Characteristics of a Real Amethyst
Before you begin testing your amethyst, it’s crucial to understand what to look for in a genuine amethyst stone.
Here are the key characteristics:
1. Color
The most noticeable feature of an amethyst is its color. Real amethyst ranges from light violet to deep purple, and it often has different shades within the same stone. The most valuable amethyst stones are typically those with deep, rich purple hues.
However, a real amethyst should not appear too bright or unnaturally purple. If the color seems too vibrant or artificial, it could be a sign that the stone is synthetic or treated. Additionally, the color should be consistent throughout the stone without any patches of pale or uneven coloring.
2. Transparency
A genuine amethyst stone is typically transparent to translucent. It should allow some light to pass through, although it may appear slightly cloudy in certain areas due to internal inclusions. If the amethyst is completely opaque, it’s likely not real.
3. Hardness
Amethyst has a hardness rating of 7 on the Mohs scale, meaning it is relatively hard and durable. Real amethyst can withstand scratches from materials that are softer than 7, such as glass or plastic. If your amethyst is easily scratched or chipped, it may be a fake.
4. Inclusions
Like many natural gemstones, amethyst often contains natural inclusions (internal flaws) known as “birthmarks.” These inclusions can appear as tiny bubbles, crystals, or streaks inside the stone. If you observe inclusions under magnification, it’s likely a real amethyst. A lack of inclusions may suggest the stone is synthetic.
How to Test if Your Amethyst Is Real
There are several methods you can use to test whether an amethyst is genuine or fake. Some tests require specialized equipment, while others can be performed with items you already have at home.
1. The Scratch Test
Amethyst has a hardness of 7, which means it should not be scratched by anything softer than itself. To perform the scratch test, take a piece of glass, steel, or another material with a hardness of less than 7. Try to scratch the surface of the amethyst with this material. If the stone scratches, it’s not real. If it remains unscratched, it’s likely genuine.
2. The Cold Test
Amethyst is a naturally cold stone when you first touch it, and this coldness lasts longer than other materials. To perform the cold test, simply hold the amethyst in your hand. If the stone feels cool to the touch and retains that coolness for several seconds, it is likely real.
3. UV Light Test
Another way to test amethyst is by using ultraviolet (UV) light. Under UV light, genuine amethyst may show a faint fluorescence, often a blue or purple glow. While not all amethyst stones will fluoresce, if the stone doesn’t exhibit any reaction under UV light, it could be synthetic.
4. The Water Test
This is a simple test that involves submerging your amethyst in a glass of water. If the stone floats on the surface, it is likely a fake because real amethyst is denser and should sink. However, keep in mind that this test is not foolproof, as some fakes may sink as well.
Common Types of Fake Amethyst
It’s important to be aware of the various types of fake or synthetic amethyst stones. Understanding these types will help you better identify a genuine amethyst.
1. Synthetic Amethyst
Synthetic amethyst is created in a lab and has the same chemical composition as natural amethyst. It is often harder and more uniform in appearance, but it may lack the unique inclusions found in natural stones. While synthetic amethyst can look convincing, you can usually tell it apart by its perfect clarity and color.
2. Heat-Treated Amethyst
Some amethyst stones undergo heat treatment to enhance their color. While heat treatment does not make the amethyst fake, it may alter the stone’s natural characteristics. Heat-treated amethyst may exhibit deeper hues of purple and a more uniform color, but it can be less valuable than untreated stones.
3. Glass Imitations
Glass can be made to resemble amethyst, and it is often sold as a “gemstone.” Glass amethyst stones may be easier to identify because they are much lighter than real amethyst and often have a different texture. They may also lack the natural inclusions that give amethyst its authenticity.
4. Plastic Imitations
Some fake amethyst stones are made of plastic. These stones can often be identified by their weight, as they are much lighter than genuine amethyst. They may also lack the reflective qualities and depth that real amethyst possesses.
Where to Buy Real Amethyst
If you’re looking to purchase amethyst, it’s important to buy from a reputable source.
Here are some tips for finding genuine amethyst:
1. Reputable Jewelers
Professional jewelers and gemstone dealers often have strict standards for the quality and authenticity of the gemstones they sell. Buying from a well-known and trusted jeweler can help ensure that you are getting a real amethyst stone.
2. Certified Gemstone Dealers
Look for dealers who provide certification for their gemstones. Certified dealers will often include a gemological report that confirms the authenticity and quality of the amethyst. This can give you peace of mind knowing you’re purchasing a genuine stone.
3. Avoid Online Marketplaces Without Reviews
While online marketplaces can offer competitive prices, it’s important to read reviews and check the seller’s reputation before purchasing amethyst. Be wary of sellers who do not provide detailed information or offer questionable deals on amethyst stones.
Conclusion
Knowing how to tell a real amethyst from a fake one is crucial for anyone interested in buying or owning this stunning gemstone. By understanding the key characteristics of genuine amethyst and using a few simple tests, you can confidently identify authentic amethyst and avoid getting scammed by synthetic or imitation stones.
Whether you’re purchasing amethyst for its beauty, metaphysical properties, or as an investment, always make sure to buy from reputable sources. With the right knowledge, you’ll be able to enjoy the true beauty and value of this gorgeous gemstone for years to come.
