Can you identify this for me whether it is a mineral or not, and what kind?
I've tested it and it is higher than 6 on the Mohs Scale, it is extremely smooth and resinous. I would highly appreciate it if you were a professional or currently studying in this field of science.
Thanks a lot here's a picture pic.twitter.com/PVwVH3gtvr

It is sand stone..
Incase if you don't know what it is, it is a mono-mineralic rock composed of Quartz.
It is a sedimentary rock, and the samples you photographed are fine grained, probably collected from river or some water ponds. They are less transported from the source rock.
So, you can find similar huge rock masses in surrounding areas.

They look to me like rocks. The Mohs Hardness Scale only applies to lone minerals, so I don't think it will be of much use. They look to me to have been from a river? Did you put these in a rock tumbler?
The best I can do is say these are probably sedimentary rocks. I'm having a hard time determining scale etc. thoughSource(s): Geology major
