Easily amused


Recommended Posts

I'm sure you guys have seen this before, but I picked this up yesterday cause I thought it was cool how the black had grown in between and around the crystals. Broke it accidentally when I split the rock, but now I can really see the shape it took around the quartz.

Very nice specimen you collected, well done!  My guess is that you have Quartz with Rutile, or Illmenite or maybe Magnetite.  See if it is attracted to a magnet; if not, then it could be one of the first two choices.

" Not magnetic, has a reddish brown streak."  sounds like Illmanite;  would need to do a chemical test for titanium & iron to know for sure.  The observed Pyrite would account for the yellow staining of the sample.
