Zircon comes in various colors, including blue, red, yellow, green, brown, and even colorless. Its diverse color palette often mesmerizes those who are captivated by its allure. When identifying zircon, it’s crucial to focus not only on the color but also on its luster. Genuine zircon has a high refractive index, which lends it a stunning sparkle, similar to that of a diamond. This is one way to zircon from its impostors.
Another key factor in recognizing zircon is its hardness. Zircon ranks 6.5 and 7.5 on the Mohs scale, making it relatively durable. However, it is still softer than diamonds and some other gemstones, so it should be handled with care. To test its hardness, you can use a glass plate: if it leaves a scratch on the surface, it is most likely zircon.
One of the most distinctive features of zircon is its pleochroism. Pleochroism refers to the ability of a gemstone to exhibit different colors when viewed from different angles. When examining zircon, try rotating it in different directions under a light source. Genuine zircon will display various hues, adding to its overall allure.
Additionally, zircon exhibits a unique phenomenon called metamictization. Over time, due to the presence of trace amounts of radioactive elements, zircon may experience color changes. This phenomenon is something to consider when purchasing zircon jewelry or gemstones. Natural blue zircon, for example, is created by heating brown zircon to high temperatures, inducing a color change. It’s important to consult a reputable jeweler who can provide you with accurate information regarding the origin and treatment of the zircon you intend to purchase.
Finally, it’s vital to be aware of the difference between zircon and cubic zirconia. While both share a name, they are distinct gemstones. Zircon is a natural gemstone, whereas cubic zirconia is a synthetic material designed to mimic the look of diamonds. Cubic zirconia is less valuable than zircon and lacks the inherent beauty and uniqueness of the natural gem. As such, it is crucial to examine the gemstone closely before making a purchase and to seek the assistance of a knowledgeable jeweler.
In conclusion, recognizing zircon requires a keen eye and attention to detail. By examining its color, luster, hardness, pleochroism, and understanding its unique properties, you can confidently distinguish this exquisite gemstone from its imitations. As with any purchase of jewelry or gemstones, it’s advisable to consult reputable jewelers who can provide you with expert guidance to ensure your zircon is genuine and of high quality. With its stunning beauty, zircon is a gemstone that deserves to be cherished and appreciated for generations to come.
