Description :
Crystal habit: Perfect cubes, often with slightly frosted or stepped faces Color: Your piece shows a smoky gray tone, which can come from trace impurities or natural radiation exposure Luster: Vitreous (glassy) Common localities with this look: Berbes, Asturias (Spain) Elk Creek, South Dakota (USA) Morocco Illinois–Kentucky Fluorspar District (USA) Crystal habit: Flat, bladed or tabular crystals Color: Honey‑yellow to amber, often translucent Luster: Pearly to vitreous Why it forms with fluorite: Both minerals can precipitate from hydrothermal fluids in similar temperature/pressure conditions, so they often grow together in cavities and veins. The orange and greenish granular coatings could be: Iron oxides (rusty orange) Chlorite or other silicates (greenish tones)
These are common secondary minerals that form after the main crystals.Fluorite (the gray‑translucent cubes) 7 x 5
