Yttruim Fluorite on Calcite

Yttrium Fluorite and Calcite

Yttrium Fluorite, also known as Yttrofluorite, is a rare variety of fluorite where yttrium replaces calcium in the crystal structure. This substitution results in a unique mineral with a cubic or octahedral crystal structure and a range of colors from pale lilac to deep violet. Yttrium Fluorite is often found on calcite, where it forms a microcrystalline coating that can cover the calcite crystals, creating a striking visual effect. The Qinglong Mine in China is known for its deep purple microcrystals of Yttrium Fluorite on calcite, which are not only rare but also a testament to the geological processes that create these fascinating minerals.
