Wow that is a nice piece. I was gonna say rutilated quartz, but not sure now. wonder if it is some sort of beryl. are the "rods' sided, or circular?

They are circular but they have lines going down them

Sorry but I don't think it is rutilated quartz.
The black rods are too big for rutile.
I think it is schorl, black tourmaline.
It has been tumbled by a river or lake shore a lot. I wouldn't expect to see any crystal structure left on the outside.
Also you might want to do a hardness test on the "quartz". It could be topaz.

How do I do a hardness test

Try to scratch a known piece of quartz with it.
Topaz is harder than quartz.
You might need a hand lens to see a scratch. Don't mistake the powder left by a softer rock as a scratch. Brush away any powder then look for a scratch.
I have a set of rocks for testing hardness. It has a topaz in it. It should not leave a scratch on your sample if it is topaz but will if it is quartz.

I'd also go with tourmaline. (schorl)
