I collect silver, coins and bullion....but I also really like collecting rocks! I was looking through some of the rocks we found last summer, for any that would be good for polishing. These were some of my interesting ones that were to big to be tumbled. Lighter for size reference.
Iron Ore
Iron ore is Michigan’s most valuable non-fuel, mined commodity. In 1994, the Lake Superior area produced 95% of the US’s supply of iron ore. Check out these pieces we found while visiting Iron Mountain and vicinity. They both have a nice Quartz vein in them, but it's hard to see in the pic.
Pyrite
I know 
What was that??? You want to see them a little bit closer? I can accommodate that.
Then there is this one...
I have no idea what this one is. It has the weight of a rock but is as smooth as glass. It has 2 sides that are "not polished" but very flat. The part that confuses me is the rough broken parts. It seems like they wouldn't be polished if they were broken off. It has all sorts of layers/lines of other colors going across the whole thing.
What do you think this could be? I have no idea but it looks cool. Check it out.
That's all for today. Do you have any idea what that Red Rock could be? Let me know what you think.
