Just off the top of my head, I've seen obsidian look like these pictures. Also where I am in central Alabama we have large vanes of coal and one variety is know to be on the surface of the ground where you can just pick it up by the bucket full. It's a high grade of coal for burning in blacksmiths furnaces as well as a heating source for homes, and has been used that way for over a 100 years here. With the first picture showing a gold sheen I thought of Pyrite also know as fools gold, but the second picture doesn't show it. Ive also included a few possibilities that I seen getting the images of what I thought it could be .....I'm no geologist for sure but maybe I alteast removed a few possibilities from the list of what it could be lol.

Attached are images and a little information on the rock/mineral types I stated and a historical description of the town I lived in. In the forum for my first post here I had the pleasure of working on one of the original property's stated in the article. It was the first home/boarding house used on the East West Railroad replaced by the beautiful white Victorian two story you see in the article.

Happy searching and I hope this is as interesting to you as it is to me.

Can you tell us in what State it was found in and also if there are railroad tracks close by or any factories in the close vicinity.

California,
No any factories nearby.

Do you think it’s germanium ore or beryllium or something ? Does it looks like that?

Thank you

It looks a lot like Antimony to me but it's hard to tell from just a picture.
