The turquoise in this bracelet is a very good color and they are well matched.  Copper needs polished but is good.  I don't know what to use so I will set someone else clean it.   It is marked Copper USA.  One side has a slight bend in it but it could be fixed easily.  I have taken pictures including a quarter so you can judge the size of the pieces.  If you have any questions, please feel free to contact me.  I am happy to combine shipping to save on the cost for multiple items.
