Beautiful gift for the musician or music fan in your life. I believe this to be an original design. It appears to have 14KT marked but it is tiny and hard to see. I took the best picture that I could take to try and show it. This was purchased at an estate sale many years ago and has been kept in a box and worn only a few times. The information was what I was told by the family member holding the sale. Beautiful unique piece. The pin could be made into a pendant. The pearl is very pretty.
