Hi,
Apologies for the lack of description, we are very new to sites like this, so didn't add as much detail as is needed. I'm going to measure the brooch etc. Tomorrow. Will also post a pic of the back pin as requested.
From the other Victorian mourning brooches I have seen, the back looks very similar, but as I said we are new to this! We are a couple, and this was a Christmas present from my fiancé. I love the Victorian era, and love to collect various pieces from that time, it's always lovely to find out what it is that I now own.
Thank you for the replies, you've all been helpful. I will get back to you tomorrow, thanks in advance for the help. There are no markings on the back, so we have hit a dead end as we are unsure what to look for. Again, apologies for the lack of description and knowledge on our part!
