Formation and Composition
These stunning fluorite clusters are sourced from Yindu, Inner Mongolia, a region known for its rich mineral deposits. Fluorite, primarily composed of calcium fluoride (CaF₂), forms in a cubic crystal system, giving these specimens their distinctive geometric shapes. The specimens may exhibit a range of purple and green color zoning, a natural phenomenon caused by different trace elements, such as iron or rare earth elements. Some pieces are adorned with quartz inclusions, adding to their visual allure and sparkle.
Care Instructions
To preserve the vibrant colors and natural beauty of your fluorite specimens, it’s important to handle them with care. Fluorite ranks at 4 on the Mohs hardness scale, making it relatively soft and susceptible to scratching. Avoid exposure to direct sunlight for prolonged periods, as this may cause the colors to fade over time. Clean gently with a soft cloth or rinse with water, but avoid harsh chemicals.
Interesting Facts about Fluorite
- Fluorite is highly prized for its fluorescent properties – under ultraviolet light, many fluorite specimens glow in brilliant colors.
- It's known as the “Genius Stone” for its reputed ability to enhance concentration and clear thinking.
- Fluorite often forms in association with other minerals, such as quartz and calcite, creating beautiful and complex specimens like these.
- The distinct purple and green color zoning in these specimens is a result of trace impurities, with purple indicating the presence of yttrium and green often due to iron.
These Purple and Green Fluorite Clusters are not just visually captivating, but also a fascinating natural wonder that will enhance any mineral collection or serve as an inspiring piece of décor.
