photos of the rocks
Hi Jacquelyn -
The silver sparkly bits are Mica. I have several just like those out front. The one toward the bottom that you're holding in your hand, looks like a
Chert nodule. I have a couple of those too. You should get quite a few replies, with intelligent answers.
We're a bunch of rock heads....er...hounds!.

I just looked at your rocks and it looks like most of them are quartz. The round black one looks like a piece of asphalt cut from a road. The gray
with dark specks looks like a piece of granite. As for the quartz it is possible that the gold flakes are in fact gold. I can't tell for sure from the
pics but that is where gold is found. Silver is also found in quartz though rare. I would take those white "Milky Quartz" the be tested if you see a
dark stripe through it. You do also find mica or fools gold in quartz so it may not be worth being tested unless you have a lot of it.
It is hard to be sure from photos but that is my best guess from what I can see.
