What is Tourmaline?
Tourmaline is a gemstone known for its diverse range of colors and unique properties. It belongs to the boron silicate mineral group and is often referred to as the "birthstone" for October. The name "tourmaline" comes from the Sinhalese word "toramali," which means "mixed stone," reflecting its diverse color palette.
The color of tourmaline can vary from pale pink to deep blue, and even include multiple colors within a single crystal. This gemstone is also known for its ability to be piezoelectric, meaning it generates an electric charge when subjected to pressure.
Identifying Tourmaline:
Now that you know what tourmaline is, let’s dive into the techniques for identifying it.
-
Color:
One of the most distinctive features of tourmaline is its vibrant color. While it can come in a wide range of colors, tourmaline is often characterized by its intense and pure color. Look for gemstones with a clear, bright color that stands out against its surroundings. -
Crystal Shape:
Tourmaline crystals are usually elongated and prismatic, with a distinctive shape that sets it apart from other gemstones. When examining a tourmaline, look for its elongated prismatic crystals, which may be terminated by sharp, pointed ends. -
Transparency:
Tourmaline is generally transparent to translucent, allowing light to pass through its crystal structure. However, it may have some inclusions or color zoning, which are natural features that can help identify it.
-
Hardness:
Tourmaline has a hardness of 7 to 7.5 on the Mohs scale, making it a durable gemstone suitable for jewelry. Test the hardness by trying to scratch the surface of the gemstone with a metal object. If it leaves a mark, it is not tourmaline. -
Specific Gravity:
Tourmaline has a relatively high specific gravity, which means it is heavier than many other gemstones. If you have access to a balance scale, compare the weight of the gemstone to its size. Tourmaline will feel heavier than expected.
Conclusion:
Tourmaline is a captivating gemstone with a wide range of colors and properties. By understanding its unique characteristics, such as color, crystal shape, transparency, hardness, and specific gravity, you can easily identify tourmaline. So, the next time you come across a stunning tourmaline gemstone, you’ll be able to recognize its beauty and appreciate its unique qualities. Happy gemstone hunting!
