When you’re shopping for an engagement ring, it’s easy to get captivated by carat weight and clarity. But if you’re considering certain diamond shapes, you’ll also want to pay attention to something called the bow-tie effect. Understanding this phenomenon will help you find a diamond that sparkles brilliantly from every angle.
What Is the Bow-Tie Effect?
The bow-tie effect is an optical shadow resembling a bow tie that stretches across the center of a diamond. It appears because light doesn’t reflect evenly across all the facets. This effect is not a defect or inclusion—it’s simply how the stone’s shape and cut interact with light. In some diamonds, the bow tie is subtle and almost invisible, while in others, it can create a distinct dark band.

Which Shapes Show a Bow Tie?
Elongated fancy shapes are the most likely to display this effect. Oval, marquise, pear, and sometimes heart-shaped diamonds often show a bow tie to some extent. The bow-tie shadow typically runs horizontally across the widest part of the stone. That’s why it’s especially important to view these shapes in person or with high-resolution videos.

How Much Does It Matter?
A slight bow-tie effect can add character and depth to a diamond, but if it’s too pronounced, it can make the stone appear dull. The visibility depends on cut proportions, facet alignment, and overall craftsmanship. When you’re shopping, examine how the diamond looks in different lighting. Ideally, you want a stone that shows minimal dark zones and reflects light evenly.
