As a gemstone enthusiast, I have always been fascinated by the diverse world of natural gemstones. One particular gemstone that has caught my attention is zircon. Zircon exudes a unique beauty and charm, but many are unsure whether it is a natural gem or a synthetic alternative. In this article, I will delve into the world of zircon, exploring its origins, properties, and value to determine if it is a natural gem worth discovering.
What is a natural gemstone?
Before we can explore the nature of zircon as a gemstone, it is essential to understand what constitutes a natural gem. A natural gemstone is formed through natural processes, often deep within the Earth's crust. These gemstones undergo a complex geological process involving heat, pressure, and various chemical reactions. Unlike synthetic gemstones created in laboratories, natural gemstones are cherished for their rarity and unique characteristics.
Understanding zircon as a natural gem
Zircon, often called zirconium silicate, is a natural gemstone. It is formed through molten magma's crystallization or existing rocks' metamorphism. Zircon can be found in various colours, including blue, yellow, green, brown, and even colourless. Its beauty lies in its high refractive index, which gives it a brilliant sparkle. Zircon is often mistaken for cubic zirconia, a synthetic gemstone, but they are entirely different materials.
Differentiating natural zircon from synthetic alternatives
To the untrained eye, distinguishing natural zircon from its synthetic counterparts can be challenging. However, a few key differences can help identify natural zircon. One determining factor is the presence of specific inclusions, such as mineral crystals or colour zoning, which are often absent in synthetic zircon. Additionally, natural zircon may exhibit slight imperfections and variations in colour, whereas synthetic zircon tends to have a more consistent appearance.
The allure of natural zircon
What makes natural zircon truly alluring is its unique optical properties. Its high refractive index and strong dispersion give it a remarkable brilliance and fire, similar to a diamond. Natural zircon also has a mesmerizing adamantine lustre, adding to its beauty. Furthermore, zircon has a long history and cultural significance, associated with wisdom, prosperity, and protection. The allure of natural zircon lies not only in its physical characteristics but also in its rich symbolism.
The origins and formation of natural zircon
Natural zircon is primarily formed in igneous and metamorphic rocks. It can be found in various parts of the world, including Australia, Brazil, Sri Lanka, and Cambodia. Zircon crystals are typically found in pegmatites and alluvial deposits. The formation of zircon involves a complex process that spans millions of years. It begins with the crystallization of zirconium-rich magma or the alteration of existing rocks through intense heat and pressure. Over time, these processes result in the formation of beautiful zircon crystals.
Properties and characteristics of natural zircon
Natural zircon possesses several unique properties that make it a sought-after gemstone. Its hardness of 6.5 to 7.5 on the Mohs scale makes it suitable for everyday wear. Zircon also exhibits a high refractive index, ranging from 1.78 to 2.01, giving it exceptional brilliance. Its dispersion, which measures the ability to separate white light into spectral colours, is also relatively high. Additionally, zircon is known for its pleochroism, meaning it can display different colours from various angles.
The value and market for natural zircon
The value of natural zircon varies depending on several factors, including colour, clarity, size, and origin. Blue zircon is highly prized and often commands a higher price, while colourless and yellow zircon are more affordable. The market for natural zircon has been steadily growing as more people recognize its unique beauty and rarity. Collectors and gem enthusiasts are particularly drawn to natural zircon due to its historical significance and ability to rival other gemstones in beauty and brilliance.
Caring for and maintaining natural zircon
Proper care and maintenance are crucial to ensuring the longevity and beauty of your natural zircon jewellery. Like any gemstone, zircon should be protected from harsh chemicals, extreme temperatures, and physical impact. It is advisable to remove zircon jewellery before engaging in activities that may subject it to undue stress. Regular cleaning using mild soap and a soft brush is also recommended to keep your zircon jewellery looking its best.
Conclusion: Embracing the beauty of natural zircon
In conclusion, zircon is indeed a natural gem worth discovering. Its unique properties, mesmerizing beauty, and rich symbolism make it stand out in the world of natural gems. Natural zircon offers a captivating option, whether you are a collector, a gem enthusiast, or looking for a distinctive piece of jewellery. So, embrace the beauty of natural zircon and let it add a touch of elegance to your jewellery collection.
