The last picture is of a matching guitar string necklace that is also available in my shop: http://www.etsy.com/listing/62089189/guitar-string-jewelry-sheet-music-paper
All of my guitar and bass string jewelry is made from previously played strings. Some strings may have some discoloration, but I feel this adds to the character of the pieces. Since most guitar strings are made up of more than one metal, for example steel and nickel, they are not able to be recycled. Unless the strings are given a new use they will just end up in the trash, which makes my guitar string jewelry eco-friendly as well as being beautiful and unique pieces of jewelry.
