Hello, second post here. I repost it in the right section.
I bought some time ago this necklace in an antique shop. I use it as a bracelet as it is quite too small as necklace for me.
I took it to a mineral shop, to a guy that seemed to know his stuff well, and after looking closely at it all around for several minutes and weighting it in his hand, he told me he was pretty sure it was real turquoise, and told me it was possibly a mix between turquoise from Arizona and turquoise from Tibet, judging from the colors.
But I would have liked to have your opinion too. There is color differences between the chips and, looking with a loupe also on most of the chips themselves, albeit more subtle. A lot of the chips also have pyrite (some quite big) inclusions in them, and the colors are not too outlandish or bright, I mean it does not comes off to me as an obvious fake.
With those elements I was quite confident that it was real indeed. But as I’m no expert at all, I’m not sure.
Do you think it might be real turquoise?
Also, like the idiot I am I tried to scratch one of the chips with a 19th century copper coin (so actual copper, not just copper plated) and it did not leave any scratch, but I don’t know if it means anything.
There is also a chip that has clearly been broken at one point and repolished, and which is blue through and through.
