Some kind of cool slab supposedly from Hachita area
« on: February 15, 2015, 12:36:06 PM »

I bought a box of small mixed slabs from ebay, and this is one of the ones that seemed to have the best potential.  I haven't had a lot of experience yet, but wow, this stuff is pretty tough.  Harder than the jaspers I've shaped, at least, so far.  And there is some matrix of some kind mixed in with the malachite, chrysocolla, azurite and turquoise the description of the slab said were in there.  The matrix seems a bit metallic in nature, and that's taking a long time to come to a polish with the setup and polishing compound I'm using.  (Some filched Loritone polish from our rock tumbling kit...)  As you can see, it's a pretty hefty cab, about 47mm x 35mm x 6mm.  I like larger cabs because stone patterns tend to be pretty large and this way you can see more of it in the finished pendant.  :-)

So, here is the progress so far.  We're going to get better polish and maybe a new polishing pad soon.  But I'll keep at it with what we've got for now and see if I can finish bringing the shine out some more.  The matrix is *finally* starting to smooth out and polish up a bit.  The last picture is where I am after the fourth polishing session.  If anyone has had any experience with this kind of material, I'd love to hear how you got the matrix to behave during the polishing stage.

Oh, me, too!  So much so that I'll have to watch what I'm doing or some variation of blues and greens will be all I ever work on.   :icon_tongue:   lol

Reminds me of parrot wing chrysocolla.  Maybe?

Hmm, I just looked this up, and it could be!  The auction description said they were selling it for a friend and didn't know what it was called, but that they'd been told it contained turquoise, chrysocolla, azurite, malachite and calcite.  And that it was from the Hachita Valley in NM.  Any or all of this is suspect, of course, since the seller said they weren't a rock hound or even very knowledgeable about rocks.  But it does look to me like they got the composition right. 

If it is parrot wing, it's a very intense cut of it - but I expect it varies considerably, just like most rocks.  And the colors and composition are right... so you may have figure out the puzzle!  I'll do some more research and see what I can turn up.  Thanks!!!   :hello2:

The usual matrix mixed in with these materials is cuprite, which is a copper based mineral.  That is one sweet slab/cab you scored there- you really worked the material well!

Thanks!  I guess the reason the matrix seems metallic, is because it probably IS metallic!  LOL.  Cuprite would totally make sense as a matrix, because of the copper content in the blue and green components of the rock.  Cool.   :toothy10:
