Irena Herrmannová is the face behind Haneri.  Her jewelry was the most involved that I saw at the fashion show.  She makes the earrings out of bronze and paints the design into the bronze.  I am not familiar with process of jewelry making, so forgive me if I butcher the terms.  From what I gathered, she uses an involved process where she solders the metal several times and has to actually solder the paint into the metal.  The final product: unique designs with fine craftmanship.  Check out her blog to see her work in closer detail.
