The diamond bowtie effect isn’t always pitch black. Many bowties are just slight shadows near the middle of the stone that are barely noticeable. Almost all marquise, oval, and pear-shaped diamonds have at least some bowties in them, but they are just often seamless and not so obvious.
Всъщност, certain bowties are even viewed as a positive – if the bowtie effect isn’t too pronounced and if the cutter has shaped the stone well around it, the bowtie can even add a degree of scintillation to the stone and enhance its sparkle, like this one. Oval, pear, and marquise-shaped diamonds with absolutely no bowties can sometimes look dull and boring.

Another thing to keep in mind with bowties is that dishonest vendors will often try to twist what we just said and claim that bowties are always a good thing. It’s common for many retailers to tell customers that bowties are unavoidable in elongated fancy shapes and that they enhance the beauty of a stone.
This is all false. Lighter bowties can have a certain positive effect on the stone’s appearance but overall, this effect is considered a negative on the diamond’s appearance.
