If you've ever browsed second-hand or antique jewelry, you might have come across a Swiss-cut diamond. It’s not as common as the modern round brilliant cut, but it holds a unique charm—especially for those who love vintage or unique pieces. At Serendipity Diamonds, we often see Swiss-cuts in antique jewelry that comes through our shop for repairs, remodelling, or refinishing. So, what exactly is a Swiss-cut diamond, and how does it compare to other cuts like the brilliant cut?

What is a Swiss-Cut Diamond?

Think of a Swiss-cut as a hybrid between the single-cut and the modern round brilliant cut. The Swiss-cut evolved from the double-cut diamonds of the early 1600s, which typically had 34 facets (16 on the crown and 16 on the pavilion). Over time, the Swiss-cut developed with a shallower pavilion, improving internal reflection and reducing the size of the culet (the flat bottom of the diamond). This change gave Swiss-cuts their distinctive brilliance and sparkle.

How Does the Swiss-Cut Compare to the Brilliant Cut?

The modern round brilliant cut, with its 57 or 58 facets, is designed to maximize sparkle and brilliance. Swiss-cuts, on the other hand, have fewer facets—usually 58, but with a shallower pavilion and a more subtle brilliance. While the Swiss-cut isn't as dazzling as a modern brilliant cut, it offers a softer, more vintage sparkle that many people find charming.

The Challenges of Replacing Swiss-Cut Diamonds

One thing to keep in mind if you're considering buying or owning Swiss-cut diamond jewelry: replacing these diamonds can be tricky. Since the Swiss-cut is relatively rare, sourcing an exact match for a missing diamond can be a challenge. In many cases, jewelers might substitute a modern brilliant-cut diamond, but the sparkle will differ, and it won’t perfectly match the existing Swiss-cut diamonds.

I recently worked with a customer who had a ring set with three Swiss-cut diamonds. I advised them to be extra cautious about losing one, as finding a replacement would be near impossible without altering the design or brilliance of the ring.

Why Choose a Swiss-Cut?

So, why would someone choose a Swiss-cut diamond? If you’re after a more vintage or antique feel, or if you’re lucky enough to find a piece with Swiss-cuts, it’s a lovely option. It’s perfect for those who appreciate the history and craftsmanship of earlier diamond cutting techniques, or those seeking a piece that’s truly one-of-a-kind.

In summary, Swiss-cut diamonds aren’t as popular or common as other cuts today, but they are a gem for those who appreciate vintage styles and a softer sparkle. Just remember, replacing one can be tricky, so it's worth taking extra care with your Swiss-cut jewelry!
