Between the years of 1912-1915, Henri Picq made about five or six blackened steel tiaras for Cartier.  Only three of them are known to still exist.

Unfortunately, I don’t know much about the tiaras of the Borromeo family.  The Borromeos are a very old Italian noble family whose most famous member is Beatrice, wife of Pierre Casiraghi.  She didn’t wear a tiara at her wedding but all of her sisters and her sister-in-law did.  Lavinia and Isabella wore the same tiara on their wedding day so this is likely a Borromeo piece.  Matilde wore a Fürstenbergtiara from her husband’s family and Marta wore a red coral tiara that was a gift from her mother-in-law,Paola Marzotto.  I’ve only ever seen the Borromeo women wear tiaras at their weddings.
