I have been wondering how one can judge these stones based on this picture. I am sure experience and knowledge are key, I just wished I had some more of both.
Even after reading some basic turquoise sources I am struggling to see the difference between waxed, dyed or stabilized turquoise let alone from a picture. Sigh.... still a very long way to go....

So what I sometimes presumed to be waxed/dyed turquoise or from different turquoise mines (which I thought might be the case for some of the stones on this necklace) could have been Chrysocolla.

What are the major differentiating elements betw. turquoise and Chrysocolla (besides transmitting of light)?
Anyone please??
