Anybody know?

Looks like grainy quartz with decomposed pyrites, the reds, though I think I see some small intact pyrites, the shiny metalic bits, in it.

There appears to be a rounded yellow ball sticking out lower center of the first picture. It could be just my interpretation of the photograph but pyrite shatters instead of rounding off. If I had found that I would crush it and pan the broken remains for gold.

CaliKingdom, I see you are a very-new member, so, first, welcome to TreasureNet.

Second... some friendly advice for you:
The What-Is-It? forum is the best place on the internet to get unknown MAN-MADE objects correctly identified. To get your "Nature-made" stone correctly identified, I suggest you post several closeup photos of it in T-Net's "Rocks/Gems" forum. Go here:

I would also be tempted to crush it and pan it for gold.
