What it evokes
Modern crystal practice associates fluorite with focus and with putting ideas in order: its bands of color, purple, green, or blue, are said to picture a mind that arranges its thoughts in layers.
No ancient text gives it this role, the reading is contemporary: its name comes not from a power but from a use in the forge, since it makes metals melt more easily. Kunz, discussing the topaz of Philemon, raises the possibility of a mass of “fluorspar.”
It becomes a marker: a crystal or a small octahedron on the work table, which recalls the wish to get organized.
The traditions
- 1530: the name
According to this source, Georgius Agricola described the mineral in 1530, in a printed work, noting its usefulness as a flux. The name comes from the Latin fluere, “to flow,” because it lowers the melting point of the materials being smelted. In 1852, Stokes drew the word “fluorescence” from its name.
Wikipedia, “Fluorite” (secondary) - Kunz’s hypothesis on the ancient topaz
Kunz relates that the “topaz” of ancient tradition, brought from the island of Topazos to Queen Berenice by Philemon, may have been only a mass of fluorine or a similar material. He himself sets a condition, “if this statement has any foundation,” regarding a statue carved from this stone: it is a hypothesis.
G. F. Kunz, 1913 book on precious stones (Gutenberg 57978), passage on topaz - Modern crystal practice
For contemporary authors, it is a stone of attention and of sorting out ideas, readily suggested to students. This idea has no older text behind it.

Nuances and sources
The signs and chakras attached to it vary, with no common source. The Derbyshire “Blue John” is a banded violet-blue fluorite, now rare; the name “chlorophane” refers to the variety that glows when heated. Bright, uniform colors are sometimes obtained by dyeing.

Fluorite: your questions
Is fluorite fragile?
Yes. Its hardness, 4 on the Mohs scale, is low, and it has perfect cleavage in four directions: an impact or a change in temperature can break it. Keep it alone in a cloth, avoid everyday jewelry and do not leave it near a source of heat.
Why does fluorite change color?
Its color depends on impurities and defects in the crystal, which explains the purple, green, or blue bands in a single stone. Strong, prolonged light or heat can alter it, which is why the profile advises against full sun and heat. Store it in the shade instead.
Are fluorite and fluorine the same thing?
Yes, they are two names for the same mineral, calcium fluoride. “Fluorine” is the old French mineralogical usage, “fluorite” the international term adopted today. The name of the element fluorine, like that of fluorescence, comes from this mineral.
