Hi, I am farily new to rock tumbling in general, and learning about identifying rocks. Is this rock some simple granite? It's fairly common and I picked it up at the beach. I apologize but I only have a polished photo. I didn't think of taking a picutre before I started (it didn't look that good). It was already fairly rounded by the water before I tumbled it. The background main colour is mostly beige/brown with reddish spots all over. The photo doesn't show it too much, but I got a fairly good shine on it with my rotary tumbler. It is definitely softer than Jasper or Agate. Thanks!  |

I had a guy visit my house and he had this stone he collected on a trip. He called it speckled quartzite. He could not tell me where it was from and I traded him a polished cab for a piece I could polish for myself to keep. It is definitely a quartzite. The Iron splotches are from pyrite that has decomposed into limonite. As you say takes a good polish but has some surface imperfections due to it being quartzite. I cabbed mine so did not tumble. So then it is from where in Canada? Do you know how wide an area it can be found?

Yep it's Quartzite for sure. Quartzite is a metamorphic rock that was originally sandstone before being squashed under a lot of earth. Not all Quartzite is pitted it just depends on how much pressure and heat it was squished under.

I have no idea how common it is in other places. I'll keep looking for some because I really like the look |

It’s pretty neat. Looks kinda like Goldstone without the little pieces of copper.
