| Dawsonite-Fluorite |
This sample is from Francon Quarry, Montreal, Quebec, Canada. It is shown 4.55X with a FOV 4.67mm.
I saw a sample from the same mine on Mindat and to my uninitiated eye the straws are Dawsonite while the purple crystals are Fluorite.

The straws look so delicate.
Fluorite in its purest forms us used to make fine photographic lens. It is used to make hydrofluoric acid. It is also used as a flux for smelting. Wikipedia
