This is a bit of a question mark for me, this was inside of a piece of kimberlite that was found in Wyoming while out surveying gold claims. It is hard enough to scratch a genuine sapphire so it has to be a least a 8 on the moh's if i'm not mistaken.

Found this rock in creek gravel bank where there is a variety of fill rock, a pink glimmer caught my eye. First thing was smack it open, this ain't from Texas. Looks like quartzite, my guess wants to be rough Ruby but how would it end up here? In love with the color whatever it may be. Included pics of stone my parents brought back from China, they were told it was Ruby but it has cleavage, is it Anyolite?
