The Carre cut looks so similar to the Asscher that often people mistake the two. However, there are distinct differences in the appearance of these two diamonds. And these differences are derived from the fact that the Carre has corners whereas the Asscher doesn’t.
asscher vs carre cut side by side
The Asscher cut is square in shape but has truncated corners. This effectively makes it an eight-sided figure with short edges. Because of this, the Asscher cut has a windmill-like appearance when viewed from the top, with the facets of the four shorter edges contrasted against the facets of the longer edges.
The Carre cut only has four sides, which gives it a clear X shape across the center of the diamond. The four sides meet in the middle in a sharp point and the cut has an overall clean, clear appearance with a square pattern.
So, while at first glance these two cuts look similar, they are in fact, different because of the number of corners they have.
