Turquoise nugget 14” necklace

Have had this handmade turquoise necklace for about 30 years. Not sure which mine they came from but know it was in Arizona. Too many places life takes us in life and information gets lost. Something in the back of my mind says Sleeping Beauty Mine, but I cannot be positive. Each nugget is uniquely different, some even have metallic minerals in them. Absolutely gorgeous. I am downsizing and selling a few choice pieces of my jewelry.
