These are rosettes of clinoclore crystals, clustered together – the largest rosette (2.3 cm) is super. The specimen is a floater, with no point of attachment to surrounding rock. The clinochlore crystals are beautiful deep green – they look black from the edges and face-on they have very fine colour. This specimen is in very good condition (excellent for the find), with minor edge rubs in places. This is a great clinochlore specimen.

About These Clinochlore Specimens
These were found in 2011 by a geologist prospecting for economic ore minerals. The clinochlores were not considered by the propsector to be interesting specimens, and so they were only tracked down more recently. A very soft mineral, excavated by a commercial prospector looking for something else… you can imagine that most from the lot were not fine mineral specimens at all. Many of the pieces I examined looked like they had been run over by a bulldozer. Repeatedly. However, a very few are really nice, particularly under good lights, where the green becomes visible. I am not aware of any specimens from this find that were pristine – these represent the best few out of the few hundred that I saw. Good clinochlore specimens are not easy to come by, so I was very pleased to find these.
