This one is of interest to me, because I actually have this exact same pendant, which I wrote about on this forum on the thread about what piece of turquoise was the first-ever and started it all for us.
Here’s an example of a seller misrepresenting what they’re selling (hopefully accidentally but I digress…). Other than some obvious clues (it’s Navajo in the title but also Zuni in the description?), they’ve guessed everything about this. I know that mine was bought at a tourist trap gift shop in the mid-70’s in North Carolina and it’s been too many years for me to say with absolute certainty since I was a child of 7 or 8 then, but I am 99% sure it is neither real turquoise nor real silver and as likely an import.
