I know this is wrapped, but I am asking about the cab. It is certainly azurite, but I am wondering if anyone can tell me the location and if it is malachite or chrysocolla in it. Is the picture good enough to tell? I took it in the diningroom under the halogens. I've done a little research and I am thinking it could bluebird azurite. (?) This is my first azurite. I picked a small, beat up corner to try it out. It surprised me how solid and hard it is considering how crumbly it looks. It is heavy for its size, too. It was actually pretty easy to cab, but the surface isn't exactly smooth. Is this something that would need to be stabilized? Thanks in advance. ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) ![](http://www.telaformosa.com/pics/RTH/5-18-14/IMG_7534.JPG)

Hard to say where it comes from since copper minerals can take on so many different looks. I would say that, from your picture alone, it looks like Azurite with Chrysocolla and the black areas are probably Tenorite. Amazing stone and awesome job on the wrap!

I agree, Azurite, Chrysocolla and tenorite. Just got a book on rocks and minerals put out by the Smithsonian. it says that Azurite is the main mineral in Lapis and gives it the blue color. Great book... ![:)](//storage.proboards.com/forum/images/smiley/smiley.png)

I agree azurite /chrysocolla. It could be from most any copper mine. I've seen very similar from Inspiration, Ray and even Bisbee. I've had bad luck with this type of stone, even stabilized. If this piece is not stabilized you've got some great stuff.

Great book... ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) I hate to be picky but I'll bet if you double-check your book it'll say lazurite, not azurite. It's very easy to confuse the two based on the similarity of the names but they're two entirely different minerals: no copper in lazurite. Lapis Lazuli is a rock, not a mineral. Its make-up can vary a lot but the main minerals usually found in it are: lazurite (25% to 40%), a feldspathoid silicate mineral; calcite (white), sodalite (blue), and pyrite (metallic yellow). Other possible constituents: augite; diopside; enstatite; mica; hauynite; hornblende, and nosean. ![:)](//storage.proboards.com/forum/images/smiley/smiley.png)
