What is the size of the facet at the bottom of the diamond where the pavilion mains meet?

Explanation:
The bottom facet where the pavilion mains meet is called the culet, and the size of that facet is the culet size. A tiny culet helps keep the tip protected and preserves a clean appearance, while a larger culet can be noticeable from the viewing angle and can affect light performance. The other terms refer to different concepts: cuttable rough is the portion of rough material that can be shaped, crystal shape is the overall exterior form, and crystal planes are the internal lattice facets, not the bottom pavilion facet.
