The bracelet was purchased at an antique shop in El Paso, Texas, over 20 years ago. Made of sterling silver with all natural stones: turquoise and red coral. I am not certain what type of stone the pinkish-orange one is, but someone has suggested to me that it is 'fire opal'. The bracelet has a wide cuff that is adjustable, and the material is very thick and heavy. The bracelet itself is large in size. It is obvious the maker put a lot of work and detail into it. The pictures do not provide any justice to the detail and beauty that surrounds it. Unfortunately there are signs of minor wear to it: minimal scuff marks, scratches, some tarnishing, and very little chipping to the stones. It's also slightly misshapen, but it's something that can possibly be corrected if the right person, with the right skills makes an effort. It is not stamped. My guess is that the bracelet was made in Mexico. The bracelet has been polished.
