I am trying to figure out the marks on these pieces.
It appears the mark is a "434" with a "B" under it in one mark and then possibly a head facing left in one mark but I can't tell.
Can anyone shed some light on these in regards to what the marks mean?
I was told by a jeweler it tested at 18k and the diamonds are real.
All three pieces have what I interpret as the "434 B" but the other mark only appears on a single cufflink.
