Query: not what I expected

I had read the reviews on this necklace and it seemed that it was what I was looking for. After receiving it, I was disappointed. The design and the size where fine but I felt the metal the medallion was made of was inferior-I would have been embarrassed to give it to my sister. I would be cautious in ordering jewelry in the future. I have used amazon many many time in the past and this is the only time I have returned an item because of the quality. The return process was easy and very efficient.
