What is it?

[William4567]

I found this rock very small and very heavy.
It has some really interesting details about it.
If you can help me figure out what it is that would be great.pictures dont do it justice

Port Lavaca, huh?? The sun probably melted some scrap steel into the soil.

It "looks" like a dirty quartz, until you show the bottom(?) of the rock that is all cracked. Yet another photo has what looks like iron staining, which is also common in quartz. .....Beats me!

Some type of agate, maybe?
