The first one is Lapis Lazuli. But I don't know where it came from. I cut this from some rough that I bought at Black Market Minerals in the local mall. The next one I think is Amethyst. It started out purple but darkened up after I cut it. The next one is Manga Calcite. It started out with a pale pinkish hue but when I cut it, it turned white with swirls. Also purchase rough from Black Market Minerals. Also the picture is just a little bit dark. The last one has a couple of pictures. I don't know what it is, but I guess Shattuckite. The green really sparkles under direct light. Thanks for lookin'

Nice cabs Bob. Looks like you've got the dome and polish down pat!

Thanks Nate. I learned the hard way that it is much easier to put a dome on them than to attempt a flat. I think I might be able to pull of a flat on very small cab, but anything larger is almost impossible to get the scratches out. I also have some excellent reference books that read thoroughly before starting to cab. Not to mention how great everyone is here.

The green one, I am suspecting that if you have sparkly areas in it, it may be aventurine. Shuttikite that I have is a deep dark blue but can be with Chrysocola and Malichite and they are both green. No matter what they are, you are doing a fantastic job! They all look great! Fran

i don't think its Shuttikite either. That material is usually more of a blue like fran said. I can't tell from the picture what it might be.

It ground very easily, soft, in fact I was wondering how well it was going to take a polish but it shined up very nicely. The only reason I thought it was Shattuckite is because it came with a bunch of other rocks and looks the same same. They are all green. I don't know what it is then and if that's the case I don't know what the Shattuckite I bought is either because none of the stuff was labled. By the way, all of those cabs except the Lapis are quite small. I haven't measured them yet.
I just took a look at those slabs again, and it is so soft I just broke a chunk off of and end piece with my fingers and hardly no pressure at all. Could it be Chryscolla?

Hmmm, maybe mariposite? It is very soft and can shine up really well. Fran

Lapis looks like from Afganistan (almost always has pyrite). Bottom looks like mariposite.

Thanks on for the ID on the bottom one. I have a bunch of that stuff. It is very brittle and very soft. It was very difficult to saw, so I just got close to cab size and decided to grind to size. Does anyone know if that Shattukite is soft and brittle too? I tried looking it up in my rock book the closest looking was called Aurichalcite. In fact Mariposite isn't in my book either.

Shattukite is not soft or brittle...about a hardness of 7.
