Yikes! This is more than I expected. First of all I appreciate all the feedback. I also did not spend any $$ on the rough, and my wife claimed the ring so I don't have a financial bias regarding value. I just want to know what I'm dealing with. First question; Does faux turquoise come in nuggets? I cabbed this piece from the rough, and it was not a block and did not have a plastic look to it. Second, if it's not turquoise but a close cousin, what is it? Third, how do you recognize stabilized rough?
I am concerned because a friend purchased several lots of rough so I could cut for him, and I want to know if he's getting ripped.
Either way thank you all for the response and education.
I did pick up a chunk of blue stone at a fleamarket that had an odd plastic look to it. When I got home I took a lighter to it and got black smoke!!
