Understand Diamond’s Depth and Table

What is Diamond?

Diamonds are precious gems that have been admired throughout history for their brilliance. To this day, diamonds are very valuable. They are the ultimate expression of eternal love, and more and more a way to show your own identity. Apart from being one of the hardest elements, a diamond is a beautiful stone that, if cut correctly, spreads the light in the colors of the rainbow and sparkles like no other gemstone can. Know, below our best information about what is Diamond Table and Depth, ideal diamond cut and diamond cut granding.

What is the Diamond Table Facet?

The table facet is the largest facet at the top of the diamond. The name table facet comes from the flat top which makes it look like a table. The size of the table differs per diamond shape. The step cut diamonds (like the marquise) have a large table facet.

Other Importance of Diamond’s Table and Depth

What is Table Facet of Diamond

The table facet is on the top of the diamond. This large facet is surrounded by the star facet and the bezel facet. The table facet is extremely important as this facet is the most visible. The quality of the table facet is therefore of great importance.

As mentioned before, the table facet is an important part of the diamond. This is also because this facet ensures the reflection of light to the pavilion and back. The table facet determines how well the light is guided through the diamond. This ensures a good distribution of the glare.

The table width is shown in percentages of the total width of the diamond. The ratio of the table facet determines the brilliance and fire of the diamond. With a round cut brilliant this ratio is visible. If the table is larger than normal, the diamond is shallower. The same applies to a narrow table as the diamond is deeper. The images below show you a diamond with a table that is too wide, a table that is too narrow, and a correct table.

What is the Diamond Depth?

What is Diamond of Depth

Diamond depth is a significant factor in a diamond’s cut. The diamond depth is its height (in millimeters) measured from the culet (bottom tip) to the table (flat, top surface). On a grading report, it is commonly two measurements of diamond depth. The 1st measurement is the exact depth of diamond in millimeters. The 2nd is the diamond depth percentage, meaning the diamond depth about its width. The depth of is percentage calculated by dividing the total depth by the average diameter, then multiplying by 100.

The Difference between the Numbers of Diamond Facets

The number of facets on a diamond differs per diamond shape and facet pattern. It is also possible that a diamond shape does not have a kollet facet because the diamond is cut very sharply. By grinding additional diamond facets, the reflection of the light is influenced. Most diamond shapes have 56 to 58 facets. These are distributed over the diamond.

Diamond Table facet

The diamond table facet is the top part of a diamond and is therefore very important. When a diamond is set in a piece of jewelry, the table facet is the first thing you see.

Diamond Crown facet

The crown of the diamond is the part between the table and the girdle. The crown facet consists of several separate facets around the table facet.

The girdle facet is also called the girdle. It is the widest and narrowest facet of a diamond located between the crown and the pavilion. On this page, you will find more information about the Girdle of Diamond.

Diamond Pavilion faceted

The pavilion facet is the part below the girdle and the bottom of the diamond, the kollet facet. The number of facets on the pavilion differs per diamond shape.

Diamond Collar

The Kollet facet is the lowest point of a diamond. It is also the smallest facet and sometimes a diamond cutter chooses to sharpen a collet so sharp that the collet disappears. The width of the kollet facet can therefore differ greatly.

What is The Ideal Diamond Table and Depth?

Naturally, larger diamonds have the equivalent of a larger table, so you can expect a larger table balance. However, depending on how the diamond is cut and surface, the size of the table doesn’t always interfere with the size of the entire diamond. In general, consumers need to balance the beautiful and the attractive when trying to choose a large table for their diamonds.

Ideal Diamond Depth

Due to the differences in body size of diamond tables, craftsmen often rely on percentage points when scoring diamonds as opposed to the table size. In the Diamond Rating report, table sizes are rated on a scale between bad and good, and percentage points are expressed as a number.

Diamond Cut Grading

Diamond table and depth affect the overall cut of a diamond. Of all the 4 C’s of a diamond, cut is the most complex and technically difficult to analyze. To determine the cut, labs calculate the proportions of the facets that affect the appearance of the diamond. In this way, they evaluate how well a diamond reacts with light to create clarity, fire, and brilliance – all aspects of a diamond’s distinctive brilliance. The cut of a diamond also takes into description the design and craftsmanship of the diamond, including weight about diameter, thickness of the girdle, symmetry of the facets, and the quality of the cut.

Then the diamond’s cut is graded on a scale, often different by the lab that grades the diamond. The Gemological Institute of America (GIA) and the European Gemological Laboratory grade diamond cuts on a scale that include the categories excellent, very good, good, fair, and bad, while the American Gem Society uses a numerical scale of zero to ten.

Since a diamond’s cut is the best place to start when choosing the perfect diamond, take the time to research the ideal cut for your desired diamond shape.
