Internal Graining and Growth Patterns

Another aspect that can be seen under a microscope is the internal graining and growth patterns. These are lines or waves that reflect the diamond’s growth history and can impact its optical properties. Sometimes, these features are not visible to the naked eye, but under magnification, they can be quite prominent.

Grades of Diamond Clarity

Inclusions and blemishes affect a diamond’s clarity, which is one of the 4Cs (Cut, Color, Clarity, and Carat Weight) used to assess the quality of a diamond. The Gemological Institute of America (GIA) classifies diamond clarity into the following grades:

Clarity Grade Description
Flawless (FL) No inclusions or blemishes visible under 10x magnification.
Internally Flawless (IF) No inclusions visible under 10x magnification.
Very Very Slightly Included (VVS1 and VVS2) Inclusions so slight they are difficult for a skilled grader to see under 10x magnification.
Very Slightly Included (VS1 and VS2) Inclusions are observed with effort under 10x magnification but can be considered minor.
Slightly Included (SI1 and SI2) Inclusions are noticeable to a skilled grader under 10x magnification.
Included (I1, I2, and I3) Inclusions are obvious under 10x magnification and may affect transparency and brilliance.
