Requesting stone identification assistance

0 votes

Polished reddish-brown stone gifted to me a while back.I did notice that along with the red color it has thin dark streaks that actually appear to be crack-like, and the last image shows a crack the lets on a slight hint of green. Was not given any information at the time but will provide what little I have gathered with some basic research. It is not easily scratched like selenite or the such and i believe it to be at least on the 6.5-7 range on the Moh's scale as it was not scratched by the rough quartz I also have. 

Any and all information is greatly appreciated.

My best guess here is jasper. Polishing removes many identifying characteristics. Jasper is an SiOjust like Quartz. It should be near a 7.0 on the Mohs scale. It could be a quartz, chalcedony, jasper mix. The red brown color comes from iron oxide in the silicate solution as it formed.
