Diamond Culet is the point at the bottom tip of a diamond, where the facet edges converge. Perhaps many people have never heard of this term or have heard of it but still don't understand it clearly. Let's learn more about this concept in the article below.
What is Diamond Culet?
What is Diamond Culet?
Diamond Culet is the pointed tip at the bottom of the pavilion of a diamond, where the facets meet. The culet can be a facet or a very small point. The culet helps protect the diamond from damage or chipping during use.
When the facet edges of the diamond do not meet at a point, the culet will be a rough or polished surface. In that case, the total number of facets of the diamond will increase.
For example: a diamond without a culet has 58 facets, while a diamond with a culet has 57 facets.
Diamond Culet Size Standards
Most diamond pavilions have their size determined by the GIA (Gemological Institute of America). The standard Diamond Culet size levels are as follows: None, Very Small, Small, Medium, Slightly Girdled, Girdled, Very Girdled, and Extremely Girdled.
For sizes None, Very Small, or Medium, the diamond pavilion cannot be seen with the naked eye. This pavilion does not affect the appearance of a diamond.

Diamond Culet Size Standards
However, if the Diamond Culet size is Slightly Girdled, Girdled, or Extremely Girdled, light can pass through. Light will pass straight from the crown through the pavilion facets. This will reduce the brilliance of the diamond.
The size of the diamond pavilion can also be expressed as a percentage of the diamond's diameter. It is measured from approximately 1.5% to 15%.
Below are the standard ratings that can be applied as a description of the diamond:
- None (pointed), Very Small, Small: Ideal; requires care when setting the stone
- Medium: Very good; protected against chipping but not visually ideal
- Slightly Girdled, Girdled: May affect the appearance of the diamond
- Very Girdled: Will usually affect the appearance of the diamond
- Extremely Girdled: Will be visible and will greatly affect the appearance of the diamond
What is the purpose of Diamond Culet?
Diamond Culets were commonly used in Old European Cut and Old Miner’s Cut diamonds a century ago. However, today, large-sized standard diamonds are not popular. This is because when viewed from above, they can be seen and affect the aesthetics of the diamond as mentioned above.
Large and extremely large pavilion sizes cause light to escape through the bottom and make the diamond appear as a dark circle. Therefore, a diamond with a small or medium culet is always desired by jewelers and users. This is because when light passes through it, it only appears as a small point at the base, and the diamond's brilliance remains perfect.

The sharper the pavilion of the diamond, the lower the risk of chipping or damage. Therefore, some diamond cutters intentionally cut a small culet to minimize the risk of chipping.
