I picked these two up at a local antique store I know the J Yazzie ring is authentic, though a little rough. The necklace baffles me. It is marked GSJ and .925. I did the acetone test on the turquoise and got no color but it doesn’t look quite right to me. The pedant has a mother of pearls inset and pearls strung with the turquoise. What do you think? The mother of pearl is white but is reflecting my pink shirt
I think that GSJ is for a silver supply manufacturer, not a handmade piece. It is hard to tell from the picture, but I think you are right in feeling the stones might not be real. Ring is incredible, that will be a great piece to wear and showoff.
