What is The Bow Tie Effect?
The bow tie effect appears as a darkened shape across the centre of some fancy-cut diamonds. This occurs when light entering the diamond from one side is not effectively reflected or refracted out the other, resulting in a central shadow that diminishes the brilliance of your lab-grown diamond engagement ring.
Diamonds are cut with a series of facets, each meticulously angled to reflect and refract light in a way that maximises fire and sparkle. However, the asymmetrical nature of fancy shapes means light may not always be distributed evenly throughout the stone. The result: the bow tie effect.
While this effect is not always considered a flaw, it can overpower a diamond’s natural beauty when the cut is poor. The presence and intensity of the bow tie depends on proportions, symmetry, and the skill of the cutter, and is most noticeable in Pear, Oval, and Marquise cuts. However, a well-cut fancy shape lab-grown diamond, by contrast, will show minimal to no bow tie, allowing light to refract uninterrupted across the stone.
