What is a Bow Tie on a Diamond?

When shopping for a diamond, especially fancy shapes like oval, pear, or marquise cuts, you may hear the term "bow tie" mentioned. This distinctive feature can significantly impact a diamond's beauty and value. At Robinson's Jewelers, we believe an informed shopper makes the best decisions, so let's explore what a bow tie is, why it occurs, and how it affects your diamond selection.

The bow tie effect appears as a dark shadow across the center of certain shaped diamonds, resembling - you guessed it - a bow tie. This phenomenon occurs primarily in elongated diamond cuts where light doesn't reflect properly through the stone's facets. While some bow tie is nearly unavoidable in these shapes, the visibility and darkness vary dramatically between stones.

What Causes the Bow Tie Effect?

The bow tie forms due to light obstruction in the diamond's pavilion (the lower portion below the girdle). When light enters through the table (top facet) but fails to reflect back to your eye from certain angles, it creates these dark areas. The effect stems from the diamond's cut proportions, facet arrangement, and the viewer's perspective. Even expertly cut fancy shapes will display some degree of bow tie - the key is finding one where it's minimal and doesn't distract from the stone's beauty.

Evaluating Bow Tie Severity

When examining diamonds, consider these bow tie characteristics:
1. Visibility: Does it appear faint or starkly dark?
2. Size: Does it span the entire width or just a portion?
3. Impact: Does it make the stone look unbalanced or enhance its character?
At Robinson's Jewelers, our gemologists carefully select diamonds where any bow tie complements rather than detracts from the stone's brilliance. We particularly recommend viewing diamonds in different lighting conditions to see how the bow tie behaves.

Bow Ties in Different Diamond Shapes

While most common in oval cuts, bow ties appear across many fancy shapes:
- Pear shapes often show a teardrop-shaped bow tie
- Marquise diamonds may display two smaller bow ties
- Radiant cuts can develop partial bow tie effects
- Even some round brilliants show subtle bow ties if cut poorly

Choosing Your Perfect Diamond

Rather than avoiding bow ties completely (which would eliminate most fancy shapes), look for diamonds where:
- The bow tie isn't the first thing you notice
- It doesn't create obvious dead zones in the stone
- The overall brilliance and fire compensate for any darkness
Our collection of engagement rings features carefully curated diamonds where bow ties enhance rather than diminish the stone's beauty. For those preferring minimal bow tie, we recommend round brilliants or cushion cuts which rarely display this effect.
