Adam's tumbled rocks

Here are some of my more interesting finds along with some quartz from The Rock Shed:











Here is a piece of local quartzite(?) With aventurescence:

Great rocks and nice closeups.  What do you use to take the pics?  

I always have a special place for quartz but it feels like I can never tumble it well. You seemed to have figured it out.

Jason nailed the best one, but what is the blue variety?

Thanks!
I used my phone at 3x magnification to take the pictures.

Thanks Jason

That one is my favorite also. It is the only rock I have found with golden inclusions. I didn't know they were there until I tumbled it in 220 SiC.

Thanks Dillon

Here is a rock that I found in Garner, NC back in October:



The side facing the camera was where I broke off a corner. I figure that the main rock and the piece I broke off weighed around 21 ounces combined.

It was on top of the ground, and I don't know its composition, but it seemed solid and microcrystalline. So I thought it might tumble well. The small piece shaped up quickly and was polished back in January. I worked on the main piece off and on since December. Once I got it shaped and defect-free, I put it in my UV minibowl to polish. That turned out to be a mistake. It was slightly too big to move around properly and ended up being roughed up on one side.

So, I put it in a 3 lb barrel and tumbled it and ceramic with 220 SiC, 600 SiC, and 1000 SiC one week at a time in succession. Then, last Sunday I tumbled it with more well-worn ceramic and Rock Shed AO polish. Here is how it turned out (pulled it out today):




For my first time polishing something in a rotary tumbler I am qite pleased with the result.

The combined weight after polishing is about 10.25 ounces:

Very cool. Looks like well marbled red meat.
Tumbling a 5 pounder - respect!

These look great tumbling material. I am sure you will enjoy them very much.
