Shapes can also be formed by a combination of edges, curves, or both, creating a closed space. Psychologists believe that the human mind decomposes images into simpler geometric shapes, known as geometric primitives. Circles and spheres are examples of geometric primitives.
Shape categories:
1. Princess Cut: This shape features raw, pointed corners and a bright cut. The typical shape is square rather than rectangular. This cut is often used in vertical crowns, with a wider base tapering to a narrower waist, and the crown facets radiating. Princess cuts typically have 76 facets, which make them brighter than bright round cuts.
2. Emerald Cut: Typically rectangular, the old square cut is still seen occasionally. This cut style has 48 to 50 facets, resembling a staircase shape, and is usually longer and narrower. A typical size for a 1-carat emerald-cut rectangle is 7 by 5 millimeters.
