I was wondering if it's just some kind of coal (though when I compare it to pictures I googled it's...

Hi everyone: I came across these two rocks at a gem and crystal shop, but unfortunately didn't catch their name. Despite their unique shape, i'm having quite a hard time identifying them. I've tried searching online but to no avail. Has anyone seen anything like these before? I know that...

I was eating at jack in the box near my house and I went for some treasure hunting again, and went searching off side from the rail road tracks near my house again and found this malachite (possibly). Question: Does it natural or used? I just found it tonight from inside the dirt/ground.

It has a bit of a reddish sheen in the light, and pretty decagonal, but very etched. Anyone have any ideas? This piece is egg sized, crystal is 2/3 size of a penny. any ideas?

I'm a lapidary artist and a lifelong rockhound and I cant tell if this is a fossil or a mineral formation? size approx. 1 1/4'' in.

I found this Rock about 20 years ago when I was a child in an area in Pennsylvania where they were digging up a foundation for a new house. I have always wondered what kind of rock it is, but could never seem to find any good leads. I would appreciate any help.

I bought a huge lot of random antiques at an auction not too long ago, and found this necklace in it. Not sure what it's made out of. Looks like it has silver and gold, or fools-gold maybe. I'm not sure if it's supposed to look like a Moral mushroom or what. Anyone have any ideas?

Hello Guys Thanks for all the help! :) Would you be able to have a look at this pictures and help me to identify this strange mineral.
