I like fluorite as well. It is a challenging material to work with though because it is relatively soft...to cut/polish effectively specialized tools would be required (which I don't have). There are many different 'varieties' of fluorite from different locales. Photo #6 is Mexican fluorite in a Quartz matrix. Quartz is substantially harder than the fluorite so it wears down slower and the fluorite grinds away in the tumbler and creates uneven pieces. I know a lot of people who tumble rocks will avoid fluorite completely, the hobby itself tests ones patience, and soft material compounds the level of difficulty/aggravation. I do find rock tumbling is significantly less taxing on my patience based than double-triple recessive ball python morph projects.![]()
