When it comes to gemstones, sapphires are known for their stunning blue hues. But did you know that there is a rare type of sapphire that can change color? Natural colour changing sapphires are a marvel of nature, captivating gem enthusiasts and collectors alike. In this blog post, we will explore the unique characteristics of these mesmerizing gemstones and delve into the science behind their remarkable color-changing abilities.
What are Natural Colour Changing Sapphires?
Natural colour changing sapphires, also known as color-change sapphires, are a variety of corundum, the same mineral that forms rubies. These sapphires exhibit a phenomenon called pleochroism, which means they can display different colors when viewed from different angles or under varying lighting conditions. The most common color change is from blue in daylight or fluorescent light to purple or violet under incandescent light.
What Causes the Color Change?
The color change in natural colour changing sapphires is due to the presence of trace elements in the crystal lattice of the gemstone. The two main elements responsible for the color change are vanadium and chromium. Vanadium causes the sapphire to appear blue, while chromium gives it a pink or purple hue. The balance between these elements determines the color change effect.
How Rare are Natural Colour Changing Sapphires?
Natural colour changing sapphires are incredibly rare, making them highly sought after by gemstone connoisseurs. Only a small percentage of sapphires exhibit this unique color-changing property, and the intensity of the color change can vary. The most prized colour changing sapphires display a vivid blue to purple transformation.
Where are Natural Colour Changing Sapphires Found?
These captivating gemstones are found in various locations around the world, including Madagascar, Sri Lanka, Tanzania, and Burma. Each location produces sapphires with their own distinct color change characteristics, adding to the allure and diversity of these gemstones.
How to Care for Natural Colour Changing Sapphires?
Like all gemstones, natural colour changing sapphires require proper care to maintain their beauty and longevity. It is recommended to clean them with warm soapy water and a soft brush. Avoid exposing them to harsh chemicals or ultrasonic cleaners, as these can damage the gemstone. Additionally, it is advisable to store them separately from other gemstones to prevent scratching.
The Allure of Natural Colour Changing Sapphires
Natural colour changing sapphires are a testament to the wonders of nature. Their ability to transform from one color to another is a captivating phenomenon that has intrigued gem enthusiasts for centuries. Whether you are a collector or simply appreciate the beauty of gemstones, a natural colour changing sapphire is a unique and exquisite addition to any jewelry collection.
Next time you gaze upon a sapphire, take a moment to appreciate the remarkable world of natural colour changing sapphires and the science behind their enchanting color transformations.
