WHAT DOES CULET MEAN IN DIAMONDS?


When shopping for a diamond, you might come across the term “culet.” But what is a diamond culet? Let’s dive in and find out!

 


WHAT IS A DIAMOND CULET?


A diamond's culet (pronounced kyoo-lit) is the tiny point at the pavilion's base, where the facets of the pavilion come together. The pavilion facets are equally cut at the right angle and meet at a perfect point, leaving no culet (sometimes called a pointed culet) in most diamonds. However, when the pavilion facets do not align at a point, this produces a culet, which is a rough or polished facet.


While a pointed culet does not add a facet to the diamond's total number of facets, a culet does. For instance, a brilliant round diamond with a faceted culet has 58 facets, compared to 57 for a diamond with a pointed culet.



IS A DIAMOND CULET GOOD OR BAD?


Although culets were commonly used in Old European Cut and Old Miner's Cut diamonds a century ago, large culets are now not favored by modern diamond cutters because they are visible through the table facet when you view a diamond from above.


A large, very large, or extremely large culet acts like a window parallel to the table of the diamond, allowing light to pass through the bottom of the diamond and giving the culet the appearance of a black circle.


Although not having a culet is the ideal option, a diamond with a small or medium-sized culet will appear to have a point at the pavilion's base, perfectly reflecting the light that passes through the stone.



CULET RATINGS:


The following are the typical rankings to describe a diamond culet:


  • None (Pointed), Very Small, Small: Ideal: You should exercise caution when setting this stone.


  • Medium: Very Good; chip-resistant, but not visually ideal.


  • Slightly Large, Large: Could impact the diamond's look.


  • Very Large: Usually distorts the diamond's look.


  • Extremely Large: Highly noticeable and will change the diamond's appearance



WRAPPING UP:


So, there you have it. The diamond culet is a tiny point at the pavilion's base where the facets of the pavilion come together. A diamond without a culet is ideal; however, if your diamond has a small or medium-sized one, then it won't significantly impact the stone's appearance. So keep an eye out for culets when you go diamond shopping! Good luck, and happy hunting!
