Maybe not! 

While we’ve discussed a lot about the 4 Cs of diamonds, we’ve barely touched upon the diamond anatomy.

That’s why we’ve put together this guide for you to understand the anatomy of diamonds. 

Let’s get started.

The Different Parts of Lab Grown Diamonds

Whether your gemstones are mined or cultured diamonds, they will have the same anatomy. Apart from the same chemical properties, they also have the same physical features.

Here’s an illustration that shows the diamond anatomy.

1. Table

The table of the lab-grown diamond is the largest facet, located on the top of the stone. 

• The table size of a diamond graded “excellent” will be between 52 and 62 percent of the diamond girdle diameter.

2. Crown

The crown of the diamond is the facet between the table and the diamond girdle.

3. Girdle

The diamond girdle is between the crown and the pavilion. It is the perimeter of the diamond. 

• Most experts recommend a girdle that is not too thick, as they look bulky and add additional weight to the diamond. 

• An extremely thin diamond girdle could increase the chances of damage to the diamond. 

4. Pavilion

The pavilion of the lab grown diamond is the bottom part between the girdle and the culet. It gives the bottom part a conical shape. 

• The pavilion of a lab produced diamond has to be of the correct depth—too deep or too shallow will lead to light escaping and affect brilliance.

5. Culet

The culet is the bottom most part of the diamond. It is a tip or a point—the portion that goes into the jewelry setting.

The diameter is measured as the width of the girdle. 
Now that we know what the different parts of the lab grown diamond are called and their specifics, let’s also understand the diamond 4Cs and what they mean for the different diamond parts.

The 4 Cs of Diamonds

Cut

Rough lab-grown diamonds have to be cut to get a desired shape out of them. However, the word "cut" doesn't only apply to shapes like round, oval, heart, pear, etc. Diamond cut also provides a diamond with its angles, facets, proportions, and finishing. The lab produced diamond's cut determines its performance and brilliance, making it the most crucial element.

Here’s the standard diamond cut grade chart to help you choose the best lab grown diamonds. 

• Excellent cut or ideal cut

• Very good cut

• Good cut

• Fair cut

• Poor cut

Color

Although diamonds appear colorless to the naked eye, a closer inspection could reveal some hues or colors. Moreover, there are a wide range of colored lab-grown diamonds as well. Diamond colors are ranked in alphabetical order. 

• D is regarded as the ideal shade for a diamond. 

• As the diamond color begins to turn yellow or brownish, they are graded as E, F, G, H, and so forth.

Clarity

Another of the 4 Cs of diamonds is clarity. Clarity refers to the diamond inclusions (internal characteristics) and blemishes (external characteristics) in diamonds. Inclusions and imperfections are graded according to their size, type, and location.

Carat

Carat weight is another of diamonds’ 4Cs. A diamond's weight is measured in carats. Carats weigh 0.200 grammes. 100 points can be used to divide up each carat. Some of the popular carat weight sizes are: 0.5 carat, 1 carat, 1.5 carat, 2 carat lab diamond, 2.5 carat, 3 carat, 4 carat lab grown diamond, and 5 carat.
