[QUOTE="Lefty, post: 267151, member: 2976"] Yep, that looks like fluorite Barney. Thing is, it's highly variable-looking stuff. I've seen it everything from monochrome crystals to multi-coloured massive bits that look like banded agate. Scratch testing is a pretty primitive - but there is a vast difference between the hardness of agate and fluorite. I would use agate as a cabochoned stone for setting, I doubt I would bother with fluorite despite how nice it looks, it's so much softer it wouldn't stay nicely polished for very long. [/QUOTE]
