[Source] High Quality Silver Brooch Pins

I know this might seem like a rather basic request, but I would like
to get some feedback sources outside of my own back yard.

I am looking for highest quality 925 Silver brooch pins and having a
problem finding a good source. I am especially looking for the kind
with a catch that has a spring loaded sliding end cap that pushes in
on the pin. The ones I presently am using are from a good US
supplier and have the rotating high quality brooch. Looking for the
best quality on the market.

Also any other source or design suggestions would be appreciated.
Anyone have experience in fabricating their own?

Best Regards,
