Recently i bought some turquoise that contained stones from a variety of mines. Among it is a stone that really intrigues me, it has 2 types of spiderweb in it, one reddish and one more towards a black color.
I haven’t seen this before and am wondering which mine(s) were capable of producing this look. Would like to investigate -and hopefully find- more.
What is known is that it was mined in the USA, in the 1960s/70s and that it was stabilized.

Whatever the mine, it’s really stunning. How big is this? Maybe you can put a coin next to it to see the dimensions, that might also help identification. Also typically your great photos are sharper 
Thanks a lot for sharing.

Thanks! I’ve made a quick pic with coins for size reference. Will try and make better ones with proper daylight.

Oh, I see one more old coins collector here 
Sorry - off-topic - here some random “coin-silver” that I’ve acquired lately, which is just on short visit at my home on the way to my safe place. All .900 (and .903) circulation silver. Native Americans have used such for a long time to create jewelry. Well, I assume they rather used the two high-mintage Mexican ones and hopefully not the two rare American ones. I assume they have used tons of mass-minted US Morgans and Peace Dollars.
Btw, the Canadians have minted a huge amount of most beautiful .800 silver coins. I wonder if these have also been used for NA jewelry. Here some of mine, unfortunately not in reach currently. I think the designs are just brilliant but the silver looks cheap compared to sterling or .900, even a bit like aluminum coins.
But don’t want to derail this thread … back to your question

Hee, those look nice! Thanks for adding them plus the background info.
I am not a coin collector really (although i cherish the old silver coins that i’ve found while metal detecting).
I bought the silver dime because it seems to be the most used US standard for measuring size in the turquoise world.

I love the turquoise.
Been a coin collector since the 1960’s.

So, i had been messaging with the seller for a bit. He is always very responsive and helpful. While he didn’t want to call it x,y or z, he did say that he had seen similar webbing formations in Seven Dwarfs turquoise, even though the colors and webs were off compared to my example.
I could clearly see what he meant, especially with the colored sections mixing, so i did a little dive into Seven Dwarfs turquoise. I find it very interesting and pretty material. It seems to regularly contain a mixture of turquoise and variscite if i’m not mistaken. I’ll add some pics of what is said to be SD material, since i couldn’t find any mention of it in the database.

That’s pretty cool! The third pic from the bottom almost looks like variscite, so I googled it. Apparently it is believed by some to be a mixture of turquoise and variscite. I think I read the mine is in NV.

While I really love the look, I aim to purchase only “real & pure” turquoise.
Nevertheless the second last one (green & blue spider with orange matrix) will look really stunning after polishing it. While I find it interesting to see the matrix looking like a layer of dirt in this case.
Found this one to be quite interesting

Yes, that’s probably the most detailed article on it. It also states that the mine is active again. I checked and it’s true. I find it quite interesting, really like some of the multicolored micro-web stones. Apparently Seven Dwarfs material was pretty rare to come by before they reopened the mine.
