Large Blue Cubic Fluorite Crystal Specimen- 276 g - (1)

Fluorite is a colorful mineral composed of calcium fluoride, celebrated for its wide range of colors and its distinctive cubic crystal habit. Large cubic fluorite crystals are especially prized by collectors because natural crystals of this size and shape showcase the mineral’s perfect cleavage and vibrant transparency. Fluorite crystals fluoresce under ultraviolet light, adding to their interest and scientific value. This 276-gram specimen demonstrates the mineral’s cubic growth pattern with well-defined edges and faces, providing an excellent example of natural mineral geometry. Fluorite is used industrially as a flux in steelmaking, but specimens like this one are primarily appreciated for display, study, and collection purposes.
