Nice job Tony, the Chrysocolla/Malachite mix is just a surface layer, the dark areas are the matrix.

Well done! I find it safer to drill the hole in the slab, and then cut the cab.

I broke a piece off the slab I had and cabbed it just to see what would happen. It had a metallic smell as I was grinding it(no surprise there) and it took a high gloss shine-almost looks like chrome, although the pics don't show it. You can see in the pics the lime green/yellow specks, and with a 10x loupe I can see they look like crystals. Even polished, the casting marks are still evident. I did a scratch test on a tile, gray/silver, but what was interesting was I chipped the metal with the ceramic tile, so it is brittle.

Well people, we've been barking up a wrong tree. My wife works in the Aerospace industry and she has a friend who has a masters degree in Metallurgy. She took the slab we cut to him and his finding is it is…..drumroll please….CAST IRON. He basis this on the porosity(5-10%), the casting marks, it's semi brittle(when we hit it with a hammer it broke off easily), and the color(dull gray) indicates a higher carbon content, which makes it very hard also. Cast Iron is tough to cut, but if it's whacked, it'll break. The military used the heaviest, cheapest metal in their bombs, something that would burst apart on impact, but be heavy enough to penetrate an object.
Colbalt and Nickel are only made in a super nova, hence the nickel and gemstone meteorites.
Sorry I couldn't have something more exotic, but it's been a good conversation piece. I really feel badly about your saw blade Tony. Who could have known? So I guess I'll just have to make my fortune elsewhere!

My wife and I are planning to be there for the PowWow, not sure what we can bring with us. We'll be staying at a motel, but if there are suggestions, lay them on me.

Ocean Jasper-thin slab was backed with jet Nambian Peitersite Chinese Peitersite Marfa Plume Stone Canyon Dino Bone Medicine Bow And I'll end with some Morrisonite. Next time it will be Boulder Opal. Stay tuned!

This is a weird one, I think it's some kind of glass. It looks manmade. Anybody ever seen this before? The cab and the rough. Not sure if I posted this WWR Red Plume Montana with Plumes Victoria stone Royal Sahara Jasper Graveyard Plume Arizona Plume Nambian Peitersite
