What’s the Difference Between Old European Cut and Round Brilliant Cut Diamonds?

Old European cut versus round brilliant cut diamonds.

If you’re not a diamond historian, you may have missed the memo that the cutting process has changed over the years, resulting in variations between cuts from the late 19th century and now. In light of this shift, one of the most commonly asked questions about vintage versus modern diamonds is regarding the difference between antique stones and today’s counterparts. Enter the vintage experts at Erstwhile Jewelry. Lucky for us, they’re stepping in to answer all of our burning cut, color, and clarity questions.

After diamond cutting became less crude in the late 1800s, the old European cut was popularized in the Victorian, Edwardian, and Art Deco periods. As technology improved, “diamond cutting techniques changed the placement and proportion of a diamond’s facets. Tables became larger, culets (the tiny point at the base of the pavilion where the facets meet) became smaller, and facets themselves became longer and leaner. These changes led to the creation of what is now the world’s most popular diamond shape: the modern round brilliant,” shares Alisa Klusner, co-founder of Erstwhile.

The differences between the old European cut and the modern round brilliant cut are how light reacts with the stones and what the two cuts were meant to enhance. “The modern round brilliant diamond and the old European cut both have either 57 or 58 facets, but the shape and placement of those facets gives each cut its distinctive personality. Whereas vintage diamonds were cut for color, modern round brilliant diamonds, as their name suggests, are cut for brilliance,” says Klusner.

With modern diamonds, light is intended to go into the diamond and bounce back brightly. Antique stones capture light in a way that draws the eye in rather than immediately sparkling back out.

Partial to the latter? Erstwhile is too—that’s why the by Erstwhile collection uses antique stones and mixes them with their modern aesthetic to create contemporary heirlooms.
