Broken Mikimoto brooch..can it be fixed?

Anyone ever had a Japanese brooch catch fixed? It is missing it's inside toggle switch, that looks like 2 rabbit ears. I have several extra toggles (rabbit ears) but normally this is just a pressure fit...this one seems to have bars holding the sides together. Any hope?

If you contact Mikimoto America, they can fix it for you. They fixed an earring for me. It's not going to be cheap, but they'll do right, especially if you want the value of a Mikimoto piece to remain valuable and not have a regular jeweler mess it up or make it look like it was fixed.

Thanks! That is the advice I was looking for!
