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.
