What is the purpose of a culet on a diamond?

Explanation:
The culet is a tiny facet at the very bottom of the diamond, aimed at protecting the pavilion point. Its main purpose is to prevent abrasion and chipping of that delicate tip during cutting, handling, and setting. If the culet is too large, it can create a small dark spot when viewed through the table and slightly affect light performance, which is why many stones are cut with a very small culet or none at all to maximize brilliance. It adds negligible weight, and it doesn’t influence how wide the girdle appears.
