The table below explains the category with the grading and its determining factors.



Determining factors

Flawless FL No inclusions are visible under a microscope
Internally Flawless IF No inclusions are visible under a microscope but a very minute on the surface of the diamond.
Very Very Slightly Included VVS-1 Inclusions are very minute and difficult to see from naked eyes.
Very Very Slightly Included VVS-2 It denotes less than VVS-1, as have a bit of more inclusions than VVS-1.
Very Slightly Included VS-1 Inclusions are very small but visible, under 10x magnifications.
Very Slightly Included VS-2 Inclusions are visible quite easily than in VS-1
Slightly Included SI-1 Inclusions are visible from the very first look under the 10x magnifications.
Slightly Included SI-2 Inclusions are seen very frequently than SI-1.
Included I-1 Inclusions can be seen without lens, with some efforts given.
Included I-2 Inclusions can be seen from the naked eyes and without any efforts.
Included I-3 Inclusions affect the brilliance and structure of a diamond, fully defective.


Fourth C: Carat

Carat is a measurement of the weight of the diamond. Diamond weight is so precise that the polished diamond is weighted to a thousandth of a carat and then rounded off the third decimal. And it’s very important to know the carat weight while purchasing the diamond.

A simple example will help you to understand about the carat.
If I want to purchase a diamond and I have a budget of say 10,000 bucks and for say the I’m looking for a diamond of 1 Carat with the color of white premium F, and it cost me like 15,000 bucks, and if I don’t have that much budget and also I don’t want to compromise on the color quality, what can I do is, I can select the diamond less than 1 carat, which can be in my budget and without compromising on my needed quality.
