I found this "rock" on the beach after hurricane irma. I found it because it set my metal detector off. it has mildly magnetic properties. seems the veins and rusty circles are magnetic but not the "stone" part. additionally this is a Florida beach that is well know to be a 1715 fleet shipwreck beach. Some have said it may be slag used as ballast stones. I personally thought it may have been from a load off of one of the ships, possibly part of the raw materials they had on board. But enough of my speculation. Do you know what it is and is it a natural stone for a Florida "treasure coast" Beach?View attachment 1512131View attachment 1512132View attachment 1512133View attachment 1512134View attachment 1512134

Slag for sure!

Found this beauty while hiking in Colorado. Caught my eye it was in a stream and never have I seen a clear rock like this one. Anyone know what it is? My guess is clear quartz1510112347931948899651.jpg20171107_202511.jpg20171107_202532.jpg20171107_202501.jpg

Images are inconclusive. I'd say there's some quartz & sulphides (pyrite?) in there.
If you're looking for gold, give the spot a closer look. Sulphides are a good sign.

Thanks! The rock is slightly magnetic. Can pyrite be a silver/white color and in thin veins like that? I can send more pictures.
 

#1 could be basalt, or other volcanic-related rock.
#2 Need better pics.

Hi! Sir Eu_citzen,

1. Same specimen but the one on the left is dry and the other is still wet.
2. Same specimen broken up.

There’s more in the stream bed.

Thank you!

It can. There's a low-temperature variation of pyrite which has a more silvery color. (marcasite, I think)
However that said, there are other sulphides with a similar look. So take it with a grain of salt, it's just a guess.

A hardness and streak test can limit possibilities.
