How Do Lab-Grown Diamonds Certify?

[navigupta]

Lab-grown diamonds are certified on the bases of the following terms to identify

Color

Clarity

Type of process used

CVD

HPHT

Each diamond goes through a grading process, and GIA and other organizations have been grading the diamonds. They give the certification report, which includes a clarity grade scale. This clarity grade scale is divided into six categories and 11 grades when seen under 10x magnification.

Slightly Included (SI) – diamonds have noticeable inclusions under 10x magnification. It is divided into two grades: SI and SI2.

Flawless (FL) – diamonds have no inclusion when seen under 10x magnification

Internally Flawless (IF) – diamonds have no inclusion and minor blemishes on the diamond surface when the trainer has seen under 10x magnification.

Very, Very Slightly Included (VVS) – diamonds have minute inclusion visible under 10x magnification. It has two grades: VVS1 and VVS2

Very Slightly Included (VS) – diamonds have minor inclusions seen under 10x

magnification. It is divided into two grades: VS1 and VS2.

Included – diamonds have apparent inclusion. It is divided into three grades I1, I2, and I3.

Thanks.. Perhaps to provide some context. Lab-grown diamonds can be certified by reputable gemological laboratories, just like natural diamonds. The certification process for lab-grown diamonds is essentially the same as that for natural diamonds, and it involves grading the diamond on the 4Cs (carat weight, cut, color, and clarity) as well as other factors such as fluorescence and symmetry. The most well-known gemological laboratories that grade and certify diamonds include the Gemological Institute of America (GIA), the International Gemological Institute (IGI), and the American Gemological Society (AGS).

It is important to note that lab-grown diamonds and natural diamonds can have the same physical and chemical properties, so it can be difficult to tell them apart without specialized equipment. This is why certification is important - it provides assurance that the diamond is genuine and has been evaluated by an independent third party. It is recommended to purchase lab-grown diamonds that come with a certification from a reputable gemological laboratory.
