- Antique Specimen
This beautiful specimen of Fluorite is accompanied by both a Fred Canfield and US National Museum tags both of which have individual identification numbers matching the numbers on the mineral (see photos). Canfield donated his collection to the Smithsonian (US National) museum and this specimen is most likely one of those specimens. It's not only an excellent antique mineral specimen but a good one at that with composite Fluorite crystals to 7mm with yellow to colorless cores and purple rims. The matrix appears to be a folded mudstone, perhaps the 'killas' mentioned on pages 4 and 107 of Embrey and Symes (1987). Refer to page 107 for a short discussion of these Fluorites probably from Trevaunance mines.

This nice green Fluorite from a classic locality shows good crystals and strong blue fluorescence, with a number of crystals showing good penetration twins. Good even color is shown though the specimen and most of the crystals are fairly transparent.
