, but Mode's latest 100 Years of Fashion video is proof that the whole "diamonds are forever" thing is real.

1920-1930s: Art Deco–influenced rings: Round early modern brilliant-cut diamond set into a platinum mounting, highlighted by round diamonds in a pierced openwork mounting.
1930-1940s: The introduction of white gold in the late 1920s; "filigree" mounting, which heralds back to the Edwardian period, comes in trend.
