Ok, I saw Tao's pix and decided to buy a couple of pieces of rough too. I managed to walk by them when I was at Quartzsite, but I began to covet them once I saw Tao's recent pix. So I admit it, HE made me do it.  (At least that's what I explained to my wife!)   The other one is on the saw now.

How large was this one Ron?

You got a lot of Azurite in yours, and from here, I don't see any fractures at all.

I don't know what size the slabs are, but what awesome cabs looks like could get if positioned so as to get all three colors on each cab.

Once you get a few beauties out of these and maybe make your Wife a nice pendant from it, she will likely say.... "Hey, what else did that Tao guy say he had good luck with"  ;D

Bbout 1/3 of slabs have a small fracture i the red area, most of the rest a pretty clean.
As to size ... 2x3+ to about 3x4


There is going to be more variety in slabs coming from the next piece, it's larger and has more bands and colors.

Ok, here is the second rock hot of off the saw. I bought this one because it had some unusual blue lines in part of it. Turns out the blue lines contained very fine blue crystals.


Single slab with fine blue line near top


Closeup (micro image) of line ...


They look too dark to be actual chrysocolla crystals, so I have no idea what they are but they are pretty. Too small to be of any value in a cab. Nice under the scope. My good camera is busy elsewhere so I used my trusty old Nikon 4500 for the micro image.

Beautiful slabs, the colors are incredible! Did you buy the rough from a source online?

It is really too bad that those same intense colors are not seen in any significant cabbing area.   

YI think you made out pretty good with that piece of rough. Really nice looking slabs.

You have green areas that the piece I have does not.

This may be a good time to straighten out my perception of what Chrysocolla is.

It is a mineral to itself, correct? Yet I have for what ever reason been thinking that examples like these are a mix of Azurite, Cuprite, and what ever the black area is. Then too some metallic veins.  By the way when you get to polishing this, you will see the metallic veins.

Maybe I am half right? These examples do have actual Chrysocolla within them (or at least the seller believes), but mixed with the others.

If Chrysocolla is a crystal then in reality there is little true Chrysocolla within the Sanora Sunrise. Not that it matters greatly, because it is a pretty group of minerals.

Maybe I should simply ask....... What part of this Sanora Sunrise makes it more Chrysocolla than a mix of Azurite, Cuprite and others?

Sometimes I think I tend to ID some of my cabs as Chrysocolla when they really look like a mix of the above mentioned.

Are those metallic veins galena?  ???

Lavender ...
I believe the gray-metallic material is likely hematite or tenorite and not galena. It does not appear to be heavy enough. Tenorite is another copper oxide material chemically similar to cuprite, but different structure. Tenorite is CuO, whereas cuprite is Cu2O.

trb ...
The rough came from good old E-Bay. They came from a dealer called ... lacasadecobre, and yes they a bit pricey but nice material. Average about $10/lb. I saw it for that much and more in Quartzsite in January.

Tao ...
The mineral chrysocolla is actually a hydrated copper silicate. And yes it does posses a true crystal shape but it is  rarely seen. What we (as lapidary people) usually see and call chrysocolla is actually the copper silicate entrapped in chalcedony. It's basically a form of crypto crystalline quartz with the blue to blue green color we all like. The small blue crystals I see maybe aruichalcite (A zinc/cu carbonate hydrate) ----  Malachite is a pure cu carbonate hydrate, as is azurite, but neither forms the small acicular blue colored crystals that I see in the vein. The blue is about correct for azurite, but it tends to form a different crystal structure.  I ca't find anyone who has done a true chemical analysis of the Sonora Sunrise thus far, but it it is said to come from a copper mine. Thus anything mentioned here might be in there.

I tell ya.... The closing prices are getting way up there.

I was outbid twice today on three chunks.

One 5 pounder that started at about 50.00 closed at 80+

Another 6.5 pounder closed at about the same.

I finally had to pay 40.00 for a 3 pounder. Plus the 10.00 shipping.

After cabbing the little that I did, sorta became more partial to the Cuprite part of this rough. So this last piece I won is solid orange.

Ron,

How is the cabbing coming along with this for you?

Cab? Who's got time for that right now? I'm reformatting pages in my book, taking more pix, have a meeting with a publisher next week up in Maryland, followed by a photo training class I'm teaching in Virginia over that week end, and this weekend I'm playing in the NC senior games in table tennis. My partner and I lost a close one in the finals today, and ended up with the silver metal in our age group in doubles. We play in singles tomorrow.

Who has time to cab right now? That sounds more like a winter indoor sport. I try to keep the saw running when I'm at home but that's about it for the foreseeable future.

I'm about 3 hours west of home right now in a motel. Will return home tomorrow night.

Wow Ron.

You do have a lot going on for sure.

I have a feeling it won't be long and your book will be on my desk. Seems like you might be at least a little excited as you get more and more accomplished.

Very exciting  :)

Good luck in the singles tomorrow, and congrats on todays silver  :)

Sounds like you're bouncing around like one of your ping pong balls doing all of that  ;)

Best of luck in your singles game! Or should it be "break a paddle"?

Thank goodness it's over. I think I will sleep late tomorrow. I lost in the semifinals, which was probably a good thing for me,  as the guy I would have played in the finals is the "winningist player" in the USA this year. He'd have et-me-up and spit-me-out!

Now I have to get things together, so I can get on the road on Wednesday for Maryland and Virginia. I think I'll be happy when next week rolls around, and I have finished my current round of obligations. This retirement stuff is getting to be too much work!

Gas is really tough where we are now, lines run up to an hour to get at a pump and there are only a few that even have it. The good news is that about an hour's drive east it is easily available, and I hear there are no problems in Virginia and Maryland. Seems it's just here in the south. Reminds me of the good old 1970's all over again. I was in graduate school n Texas back then, and we were buying gas for between $0.16 - $0.18 a gallon, and then a year later we paid whatever we had to and stood in line to get it.

I have some Utah Fancy jasper on the saw, but it has thus far been a bit of a disappointment. It's been pretty much vuggy with lots of pockets in it, and only moderately nice color. Will post some up when I get them finished in the next day or so.

---------------
Update: If I could read a calendar I would be dangerous! My trip up north is not UNTIL next week. A one week reprieve!

Just thought would share the last piece I bought. It's about three pounds.
