Well it was a new one when I bought it from a charity shop. It's a Marks and Spencer's Per Una one and I got it for almost £4. It's drop dead UGLY but the rings are really solid. The construction of the necklace was really well done with very good metal used.
I've taken it apart (it was a heck of a struggle) and now have to decide what to do with the 25 rings I've salvaged!!! I've got an idea but I'm waiting for BC3 to decide what he thinks is best.
