Has anyone here cabbed this material? Does it respond to standard cabbing methods or does it require the specialized approach used for nephrite and real jadeite? (I know it's called jadeite but it contains only 40 to 60% actual jadeite mixed with quartz and other minerals.)

wampidytoo cut some. It's extinct in nature as far as I can tell. I haven't cut it yet. I have a small piece

Ditto what Scott said. I have a couple of slabs, but haven't cut them. Interested in the answer though.

I haven't cut any, but from what I've heard, it cuts normally, but polishing can be a bit of a pain. Polishing needs to be on the dryer side -- you need to get it between the warm and hot phase without getting it too hot.

Yeah, what Robin said, I have a bit of it and, for me, it is a booger to polish past a dull shine. Don't know why as it seems hard enough. Even Washington jadeite jade I had took a better shine....Mel

Well, that's weird. I just clicked on the link above and got a message saying it's no longer available -- yet it's there. Try searching for: Jade - How to cut and polish Jade | eBay

I love this stuff. If not my first favorite stone it is no lower than third. It cuts and polishes like a very high quality nephrite. It has been a while since I worked some but I do not remember doing anything special to get a nice shine. I am sure that like any other jade there can be a large variation from piece to piece. I may have a photo uploaded. Had to go on the hunt but found some. Not one photo of the rings I made which kind of baffles me. My favorite ring stone. I believe this is a comparison of wet and dry polish. I use the Velcro backed diamond pads and I bought a set that can be used dry just for jade. the slab on the left is wet and the right is dry. Not a water shine but good light reflection. This is a personal pendant that does not get out of my sight. I have a couple of lady friends that would borrow it for a while then tell me later. The green is jadeite out of Myanmar. Hope this helps a little. Sorry I was late to the party. Jim

I've cut a number of them and they turned out good enough for Mel to comment on. I use a light touch on worn nova wheels. Seemed to work fine.

Thanks everyone for your input. I have a love/hate relationship with jade. One of the first cabs I ever cut was black nephrite from Wyoming and it turned out great. Making a ring with it for my then-wife was my first major smithing project. But that stone was cut on silicon carbide equipment that I think may be more suitable for jade.
Nearly every piece of jade I've tangled with since going to all-diamond equipment has given me problems. I'm currently experimenting with a nice moss-in-snow Burma/Myanmar jadeite cab and can see my regular approach isn't working. It's developing a grainy surface texture after sanding to 600 and I know that spells trouble ahead. I don't want to ruin it or my small stock of Turkish purple material so I appreciate all all helpful tips.

I acquired some snow white from there also but the person that bought it has zero rock experience and they took advantage of that fact. The biggest share of it is kind of punky and useless like a partially rotten piece of wood. Jim

I also have gotten better results with SiC when working jade. I think diamond is too grabby and causes the orange peel, at least with soft wheels anyway.
