Fluorite Crystal Specimen — Banded Purple, Green & Blue, 1.14 lbs — Field Find

THE FIND
A fluorite crystal specimen, 1.14 lbs — translucent bands of purple, green, and smoky blue that shift with the light. Each face reflects a different tone, as if the stone holds multiple atmospheres within its structure. A visually dynamic piece with real shelf presence.

WHAT WE KNOW
Fluorite (calcium fluoride, CaF₂) is one of the most color-variable minerals in the geological world — it occurs in virtually every color, often with multiple colors banded within a single specimen. The coloration is produced by trace impurities and lattice defects during crystal growth. Fluorite grows in cubic and octahedral crystal habits in hydrothermal vein deposits, and the characteristic color banding reflects changes in the mineralizing fluid chemistry over time. This specimen weighs 1.14 lbs and displays banded purple, green, and smoky blue coloration. Locality not independently verified.

THE STORY
Fluorite is the mineral that gave fluorescence its name — many specimens glow under ultraviolet light, a property first described in fluorite and named after it. The color banding in fluorite is a geological record: each band represents a period of crystal growth under slightly different conditions, the mineralizing fluid shifting in chemistry as the deposit evolved. A banded fluorite specimen is, in a literal sense, a timeline written in color.

WHY WE CHOSE IT
The color range on this specimen — purple, green, and smoky blue in visible bands — is broader than most single fluorite pieces show. At 1.14 lbs it has enough mass to be a centerpiece rather than an accent. A strong specimen at a fair price.
