Many people have a tendency to imagine every diamond to be like those depicted in Disney movies. However, not every gem is flawless and perfectly cut.
With its elongated and pointed edges, any slight errors in facets placement would cause an obvious misalignment of the 2 points. When choosing a stone, you would want the 2 points to be flushed and aligned to each other.
Ideally, you want to achieve a near mirror image in both sides of the diamond. On the next few pages, I will explain this in more details with photographs to illustrate what to look out for.
Girdle Thickness And Variance
A girdle thickness that ranges from thin to thick is acceptable for this fancy shape. The point to note is that you shouldn’t go too thin in order to provide mechanical strength and stability to the structure. A girdle thickness that is very thin would increase the risk of chipping in the diamond.
Bow Tie Effect
The bow tie effect is a common occurrence in fancy shaped diamonds. This usually shows up as a dark patch across the body of the diamond and can cause the stone to look darker than it should be. The degree of the bow tie effect is influenced by the cut proportions of the stone.
With that said, don’t go on a witch hunt and try searching for a marquise diamond with no bow-tie. You won’t be able to do so. What you can do is search for an ideal stone that exhibits a faint bow tie or one that isn’t obvious. I will touch on this in more details in the following pages.
