Ever noticed a dark “bow-tie” across the centre of an oval diamond? 👀💎
That’s the bow-tie effect — a contrast pattern that can appear in elongated fancy shapes when light isn’t returned evenly across the stone.
A slight bow-tie can be completely normal. But if it’s very dark or distracting, it can affect the diamond’s face-up appearance.
And here’s the important part: there isn’t a separate bow-tie grade on the certificate — you need to actually look at the diamond.
The report helps. Your eyes decide.
