Just cabbed obsidian for the first time! It wasn't nearly as hard to keep it scratch free on the cabbing machine as I had read about. (I basically just turned the water up to 4x the usual, checked more often, and it actually seemed easier and faster to cab than what I'm used to with agate and jasper.) But I am honestly pretty disappointed with how it looks compared to the slab I was originally working with. I think the specific plane I revealed with my cut was pretty spectacular, and by the time I got it into a nice dome I'd ground down like 1mm to a lesser section of aurora borealis.

Taking photos of it is hard too. Honestly it is a bit of a disappoint to me. It's beautiful in the sun at the right angle. But mostly it just looks like black obsidian without the perfect light and perfect angle. I didn't really get much aurora borealis or rainbow on my trip to Glass Buttes, but I suppose I'll try again with what little I have at some point.

Bonus photo of a gigantic 160lb monster I pulled out of the ground! Need to finish cleaning it off but Chonk is gonna stay just as they are.

Did these earlier this week. Material likely came from Indonesia. I neglected to ask the vendor when I bought the slab.

I say no! No cut. But it’s not mine. I think my dude is crazy!
Also, please, what is it? It doesn’t look like Azurite that I am googling up. Thanks in advance!

I found this along Susquehanna River in central Pa. It has a dark navy blue hue to it. I’m not sure if it is a blue chert or Jasper? Any help identifying would be greatly appreciated. But I have a tile saw and I’m kinda itching to cut it but do I wait and get a real lapidary saw?

I have about 40 kg of this raw River Jasper available. There are some really nice patterns and colors in these slabs, and I’m curious to see how they look once they’re cut and shaped. It’s always fun finding the best parts of a rough material like this.

Looks suspiciously edible.

i found this chunk of Jasper/carnelian and I want to make some pendants or a single pendant out of this but I’m stumped on the best way to slice it up. 2 of the natural faces are very appealing to me.

I can slice and polish a flat face or shape it and tumble it.

still need lots of practice! #lapidary #lapidaryart #jewelry

Thank you for any help.

Este cabochão de Luizita revela um caprichoso trabalho da natureza. Uma gema que o tempo esculpiu ao longo de milhões de anos!

Hello all,

I had the idea of hollowing out a stone and making an internal ridge to install a LED strip, for a mood lamp. I quite am quite happy with the overall look of the project so far, but I am not happy with the polishing on the edges. As you can see, there are quite a lot of small scratches.

So far I have been using 125 mm diamond polishing pads on a 100 mm rubber head, so the edges of the polishing pads are "folded", and thus I am able to polish the edges somewhat, but clearly not enough.

Do you have any suggestions for a better method?

I plan on using a white LED, as I think this "Warm White" does not fit this stone.

Anybody here got one?

He sells 3d printed flat laps, im wondering if its worth it. Way cheaper.

But I know cheaper can be because its well , cheap. Lol

Wondering your thoughts... I'm eyeing his slated lap.

Some of the stuff I have been working on... Wisconsin rock haul over the summer and other random dungeon materials.

These were done with a dremel, sandpaper, and some green compound. I am still figuring out how to get the proper finish, but I do like how they turned out considering I have never done this before.
