I found these today and have been googling without success to find anything like them. I haven't done the hot needle test as there are only about 10 beads and none are inferior to others to warrant dissection. Internally, some of the beads are streaky. The applied re-brown design is worn. If they are repro's, where are the originals and how much are those worth to go such trouble copying.

I don't trust any turquoise from China, sorry to say. I had an odd bead once in a strand I sacrificed. I broke it with a hammer. The entire inside was like a charcoal briquette. It was as if a resin had been applied to the outside.
