The listing, KAFIN NEW YORK has ended.
Signed Kafin New York on closure tab.
This company was popular in the 50's & 60's.
Choker style (approx 16") in a goldtone metal with irregular shape blue-green stone and heavy flat weave links.
Needs a good cleaning, but I do not know enough about vintage jewelry to do it myself. Also, don't know how to grade condition. Shows some wear and clasp works.
Sorry could not get better pictures. Note, not sure about spot on stone. Looks like it can be cleaned off, but again I do not want to try.
