While some engagement rings have changed a lot, others have proved to be timeless. Here's how they've evolved since 1920, according to WP Diamonds.
Just as clothing fads come and go, the most popular styles of engagement rings have changed every decade over the past century. But some designs, on the other hand, have proven to be timeless.
Since 1920, emerald-cut stones have slipped in and out of fashion, Asscher diamonds — a step-cut stone shaped like a square — have surged in popularity, and round stones have remained a staple in the wedding world.
Below, take a closer look at how engagement ring trends have evolved over the years, according to a recent infographic created by jewelry buyer WP Diamonds.
According to WP Diamonds, engagement rings with geometric shapes and sharp lines were popular in the 1920s, coinciding with the height of the Art Deco period. Emerald-cut and Asscher diamonds were especially common, and more extravagant rings were accentuated with diamond halos.
Engagement rings in the 1930s were "trying to evolve" from the Art Deco period, according to WP Diamonds' infographic. Single diamonds were often used as the centerpiece on bands shaped like ribbons or bows.
Round stones rose in popularity in the '40s thanks to De Beers' famous "Diamonds Are Forever" commercial. Rose-gold and yellow-gold bands also became common choices as World War II limited access to platinum in the US, according to WP Diamonds.
Audrey Hepburn's iconic engagement ring, which featured a trio of bands in three different types of gold, brought stackable bands into fashion in the '50s.
This decade saw the return of Art Deco, according to WP Diamonds, and with it, Asscher-cut and emerald-cut stones.
Jackie Kennedy's engagement ring from John F. Kennedy, which featured emeralds in addition to diamonds, also made colored gemstones a popular choice for couples.
During this decade, brides also began to match their engagement rings to their wedding bands, many of which were yellow- and rose-gold.
Round-cut diamonds and yellow-gold bands were still extremely popular in the '80s, but Princess Diana's engagement ring from Prince Charles, which featured a sapphire gemstone, changed the nuptials industry.
The royal ring was so popular that many replicas were made, according to WP Diamonds' infographic.
With the rise of grunge in the 1990s, rings became bolder and sharper. Marquise-cut diamonds were particularly fashionable, and yellow-gold bands took a backseat to bands made of white gold and platinum.
Many couples in the 2000s opted for engagement rings with large diamonds or stones. Taking inspiration from the '60s, the princess cut also came back into fashion.
According to WP Diamonds, the classic cushion cut is still popular today.
Skinny bands and large oval diamonds are in style, according to WP Diamonds. Usually set vertically — or, on occasion, horizontally — oval diamonds let couples play around with the appearance of their engagement rings. Celebrities like Julianne Hough and, more recently, Hailey Baldwin, are also fans of oval engagement rings.
Another huge trend in 2018 is having a custom-designed ring, as brides aim to better showcase their individual personalities.
Speaking to INSIDER, the president of WP Diamonds, Andrew Brown, said the most popular engagement ring style in the last 100 years is actually pretty simple: A "round solitaire diamond, around one carat, set on a simple yellow-gold band."
According to Brown, there will always be innovation in the diamond industry but trends often "revert to the classics."
So, what will come next? Brown thinks that round diamonds will "remain the most popular shape" while oval and cushion cuts will "continue in their rise." The WP Diamonds president also expects other trends to go out of style, like the princess cut popularized in the early 2000s.
Unfortunately for those who love colorful stones, Brown said that we can also expect to see a "decline in production of colored diamonds due to supply constraints."
