How to Spot Real Gemstones: Insider Tips from Natural Gems Belgium

In the world of gemstones, separating the real from the fake can be a daunting task, even for the most seasoned collectors and jewelry enthusiasts. With the rise of synthetic and treated stones, it's crucial to have the right knowledge and tools to ensure you're getting genuine, high-quality gems. As the leading trader of natural gemstones in Belgium, Natural Gems Belgium is here to share its insider tips and tricks to help you navigate the world of authentic gems.

Understanding the Basics of Gemstone Identification

Gemstone identification is an art that requires a keen eye, a deep understanding of the physical properties of different stones, and a willingness to put in the time and effort to learn. At Natural Gems Belgium, we believe that knowledge is power when it comes to spotting real gemstones.

Hardness and Specific Gravity

One of the most fundamental ways to identify a gemstone is by its hardness and specific gravity. The Mohs hardness scale, developed by the German mineralogist Friedrich Mohs, is a widely used tool for measuring the hardness of minerals. The scale ranges from 1 (the softest) to 10 (the hardest), with diamonds being the hardest natural material on Earth.

Specific gravity, on the other hand, refers to the density of a gemstone compared to the density of water. Each type of gemstone has a unique specific gravity, which can be used to help distinguish it from other stones. By using a simple specific gravity testing kit, you can quickly determine whether a gemstone is genuine or not.

Optical Properties

Gemstones also have distinct optical properties that can be used to identify them. These include refractive index, birefringence, and pleochroism. Refractive index measures how much the speed of light is bent as it passes through a gemstone, while birefringence refers to the ability of a gemstone to split light into two separate beams. Pleochroism is the ability of a gemstone to display different colors when viewed from different angles.

By understanding and testing these optical properties, you can gain valuable insights into the identity of a gemstone. At Natural Gems Belgium, we use specialized equipment and techniques to accurately measure these properties and ensure the authenticity of our stones.

Inclusions and Imperfections

Every gemstone is unique, and the presence of inclusions and imperfections can be a telltale sign of a genuine stone. These internal features, which can be observed under a microscope or a loupe, are often the result of the natural formation process and can vary greatly from one gemstone to another.

Synthetic and treated stones, on the other hand, tend to have fewer or more uniform inclusions, as they are produced in a controlled laboratory environment. By carefully examining the inclusions and imperfections in a gemstone, you can often determine whether it is natural or not.

Spotting Fake Gemstones: Common Tricks and Techniques

With the increasing sophistication of synthetic and treated gemstones, it's essential to be vigilant when purchasing gems. At Natural Gems Belgium, we've seen our fair share of fake stones, and we're here to share some of the most common tricks and techniques used to spot them.

The Scratch Test

One of the simplest and most effective ways to test the authenticity of a gemstone is the scratch test. Using a piece of glass or a steel file, gently try to scratch the surface of the stone. If the gemstone is genuine, it should be much harder than the glass or steel and should not be scratched. If the stone is easily scratched, it's likely a fake.

The Magnet Test

Some gemstones, like synthetic moissanite, can be attracted to a magnet, while genuine diamonds and most other natural gemstones are not. By using a strong magnet, you can quickly determine whether a stone is real or not.

The Fog Test

Another quick and easy way to test a gemstone's authenticity is the fog test. Simply breathe on the stone and observe how long it takes for the fog to dissipate. Genuine gemstones, with their low thermal conductivity, will take longer to clear the fog than synthetic stones.

The UV Light Test

Many gemstones, both natural and synthetic, have unique fluorescent properties that can be observed under ultraviolet (UV) light. By exposing a gemstone to a UV light source, you can often see distinct patterns or colors that can help identify the stone's authenticity.

The Thermal Conductivity Test

Genuine gemstones have different thermal conductivity properties than their synthetic counterparts. By using a specialized thermal conductivity tester, you can measure how quickly a gemstone absorbs and dissipates heat, which can be a reliable indicator of its authenticity.
