Fluorite characteristics
WebOolites are small, sand-sized spherical or oval grains that form as hematite precipitates from fluids. Typically oolites consist of thin concentric crystal layers that, on broken surfaces, appear as nested spheres or ovals. When not broken, hematite oolites appear to be red, well-rounded sand grains or may be mistaken for lithified fish eggs. WebFeb 10, 2024 · Fluorite is multi-colored mineral known for its powerful energetic healing properties and mesmerising physical beauty. The fluorite stone received its name from the fluorescent luminance that it emits when held under certain angles of UV light, giving it a magical glowing appearance.
