Watch One Woman Model 100 Years of Engagement Rings in Under 3 Minutes

Clothing trends may come and go, but Mode's latest 100 Years of Fashion video is proof that the whole "diamonds are forever" thing is real. But while diamond engagement rings have long been en vogue, the way the stone is presented has changed: From the lacy white-on-white look of the 1910s to 2010's "halo" mounting, see all the variations that emerged over the last century. 

Mode broke down each ring type too, for reference:

1890-1900: Classic solitaire diamond ring: Round old European-cut diamond set into a six prong mounting, 14k yellow gold.

1900-1920s: Lacy white-on-white look, in the style of jewelry of the Edwardian period.

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.

1940s: Yellow and rose gold used more.

1945: "War Bride Ring," the ring that every serviceman gave their fiancée due to the rationing of precious metals during the war years. 

1950-1960s: White gold and platinum becomes the preferred metal in postwar period. Addition of round side stones set into the shoulders of the ring.

1960-1970s: Fancy-shaped diamonds—emerald-cut, pear, marquise, and heart shaped—become in. Platinum remains metal of choice. 

1970-1980s: "Gold" set with round or fancy shaped diamonds with channel set mountings, accompanying wedding bands.

1980-1990s: Solitaire diamond with baguettes on each side.

1990-2000s: "Radiant-cut" becomes the preferred fancy-shaped diamond, typically set with triangular side stones.

 2000-2010s: "Princess-cut" becomes the preferred fancy-shaped diamond.

2010-2015: "Halo" mounting becomes the preferred engagement mounting; increased demand for fancy-colored diamonds.
