Part of Queen Victoria's crown jewels were two bar brooches that she used to anchor her sash, as shown here in the first portrait.  These two single brooches were eventually combined to make a two-row brooch, which was used for the same purpose in her later reign. 

I've reproduced both styles which are now available here!  These brooches are made with very sparkly swarovski crystals and are set in Silver-plated to mimic the originals.
