Help with identification

0 votes

Hello! I’m interested in minerals and gemstones, however I am no genius in them.

I found this rock once whilst walking near the Yorkshire coast (next to the cliffs). I was developing a mini collection at the time so I took it home. Does anyone know or have any speculation to what it may be? I have had a look on many websites and books but my I don’t really have a good eye when it comes to rocks.

Back of the rock 

There are some slight patches of crystal so on the centre and side they are smooth and are dark green. In the centre there is a tiny hole going through the rock the surroundings of the hole are dark brown with a seemingly rocky texture, however it can be quite crumbly.

There could be a chance it may be man made, but I have found no evidence.

Thank you! c:

My guess is malachite, a derivative of copper.

Malachite for sure. Not man made. If you found that, there is a good chance there are other copper minerals near that spot. Malachite is a nice find, I would recommend going back there and looking for other copper minerals if possible. :)
