You might consider changing to a roller nap with a less unified stipple to help hide stuff and create a little more texture to break up light. Something like a Purdy Colossus would be good. It’s intended for rough surfaces, but I find it work well all around, and leaves a really nice random stipple (if you lay it off correctly). I find it makes imperfections less noticeable. And maybe split the difference on sheen (flat/egg) and try matte.

It could be agatized/jasperized metamorphic rock, maybe gneiss. Those layers look pretty flat to be petrified wood.

Awesome! Love the close-ups!

Awesome find & nice polish! I love that area.

Sweet find! Love those swirls 👍

Very cool! Skip an atom inside an agate.

There’s a r/zeolites subreddit you should check out!

Sweet! Thank you for your insight. I will continue admiring it as nothing more than a beautiful chocolatey chert chunk.

Nice cut! That’s stunning! Thanks for sharing.

I think whatever wood isn’t replaced by the mineralization process ends up as coal due to extreme pressure… I often find carbon petrified wood with this stuff still attached. It’s my understanding that Jet (gemstone) is basically coal that’s been put under an enormous amount of pressure and heat.

Beautiful! 👌

Sweet! Thank you for the insight! I think you’re correct. 👍

That’s wild! Didn’t know it could look like that.

It could be fabric mesh coated in epoxy resin, commonly used for repairing fiberglass boats. But it does look like it could also be a grinding wheel.

I don’t know if that’s basalt. It looks more like a dark colored microcrystalline quartz. I see a lot of color variation and swirling going on. It’s really beautiful material!

Edit: Because my dog posted the first one.

Looks like amethyst in my opinion! Fractures in quartz can have iridescent/prism effects (crack flashing) like you see here… also, amethyst is purple because of iron; iron could explain the green/blue color of the host rock, or maybe it’s celodonite, which is common to find with amethyst.

I still think it’s carbon petrified wood. I find this stuff in SW Washington Streams. Seems it’s from the mineralization process…

“Carbon Colors: Black Explanation: Carbon is often present due to the original organic material in the wood or as pyrite (FeS₂). It imparts a black coloration, which is common in petrified wood where carbon-rich environments existed during fossilization.”

It looks like carbon petrified wood to me.

This is stunning!

Wow! Thats amazing! 🤩

Wow! That’s incredible!
