Need help identifying

[claywalker2000]

I have always loved geodes since I got my first one as a kid. A few years ago I went to New Mexico and bought one on my trip. Now every trip I take I buy a geode when I come across one.

Recently I made a trip to the Oregon Coast and I was at the Sea Lion Caves and I bought two geodes. Since I buy them I do not know the true origins of the geodes. The bigger one was a great geode to open up. But this one is solid and could not break it further. I need help identifying what I am seeing. Any help would be appreciated. Thank You.

Don't know the material of this but in order to be a geode it must be hollow. Steve in so la

What you have there are chalcedony nodules. A nodule is solid, while a geode is hollow...both same material....chalcedony quartz.

Thank you for the replies. I would assume with Chalcedony nodules it is best to have them cut?

I am including pictures of the second one I cracked open if anyone was wanting to see it. I didn't have a break that I wanted and there are multiple smaller pieces. These are the two main pieces though.

It looks like Smithsonite a Zinc Carbonate, (not sure 100%) if you find on top of other zinc, lead, or silver, deposit hosted by carbonate rock.

I found a nugget along a river bed, had it tested at a friend's Pawn shop, passed all of the tests, not lead, silver or gold, they were unable to accurately identify, where do I go now?

Take it to your local community college geology department.
Or take it to a meeting of the local rockhounding club.
Or take it to a gem and mineral show.

There will be people in all of those places that can probably identify your rock. I'm betting that you wasted your time at the pawn shop btw. (I'm hoping you didn't tell the pawn shop where you found it cause if it IS gold...................)
