Are James Allen Diamonds Certified?

Many of James Allen’s diamonds are certified by highly skilled gemologists. The certifications add to the value of your stone. They serve as evidence of the quality.

Certifications are provided by GIA, the Gemological Institute of America, AGS, the American Gem Society, and IGI, the International Gemological Institute. 

Each of the entities just mentioned ranks diamonds on the same characteristics–color, clarity, cut, and carat.

No one factor determines the value of the stone. It’s the combination and relationship of the four factors that determine the quality and value of a diamond.

What Are the 4 Cs of Diamond Certification?

The 4 Cs are the characteristics we mentioned above. 


Color is exactly what it sounds like. It’s the color of the stone. Generally, the less color the more value. Those looking for a sparkling diamond that looks like a high quality diamond want it to be as colorless as possible. 

Color is graded on a letter scale. Diamonds are ranked from D to Z. They’re also put into one of five levels.

The levels are:

  • Colorless
  • Near colorless
  • Faint
  • Very light
  • Light

Color grades don’t vary a lot from one level to the next. For example, D and E both appear to be colorless.

If you put a D-level diamond next to an F-level diamond, though, the F-level will likely appear to have a tinge of color.

The color is usually yellow because of nitrogen that’s present as the diamond is forming.


Clarity is determined by the number of flaws, or inclusions, the diamond has. Some inclusions are easily seen with the naked eye while others need to be magnified.

Inclusions can be foreign substances that infiltrated the crystals as they were growing, cracks in the stone, or even tiny holes. 

Clarity is graded on a range from flawless to slightly included. That is FL to SI. You can ensure you’re getting a good quality diamond by having the gemologist look at it to make sure there are no inclusions which can be seen without magnification.

Even one with a grade of SI could be a beautiful stone because the inclusions aren’t necessarily visible to the naked eye. It’s something that an expert can help you with.


Cut affects the sparkle more than anything else. A good cut allows the most light in to make your diamond shine. 

When gemologists look at the cut, they are looking for how symmetrical it is, what the proportions are from top to bottom, and how many facets there are. All of these play a role in how the light goes in and out of the diamond. 


Carat is the weight of the stone and coincides with the size of it. Typically, the higher the carat weight is, the more the diamond will cost. 

That being said, you could look at a diamond with a large carat weight that has a large inclusion you can see and is tinted yellow. It likely won’t cost as much as a small diamond that’s flawless, colorless, and has a beautiful cut. 

The combination of all 4 Cs determines the value.
