Stamped with 750. Italian gold necklace. I am not an expert, but a magnet did not stick to it. 50cm, 28g To prevent substitution, returns and cancellations are not accepted. There is a stamp, but since I have not had it appraised, I will treat it as a collector's item. Also listed on another site, the photos are the same as on the other site. Price negotiable. May be reduced gradually.
