Clarity |
|
|
|
|
Clarity is relative freedom from inclusions (inside) and blemishes (surface). Generally
inclusions have more influence on diamond’s clarity. These inclusions are graded
under 10x magnification in standard lighting conditions.
We divide conventional clarity grades into better and lower grades making it
more precise i.e., “VS2” clarity is divided into “VS2+”, “VS2” and “VS2-” . |

We refer to Luster as amount of overall brilliance coming out from the Diamond.
This gets affected mainly due to certain type of inclusions like heavy cloud. |

Eye Clean |
|
We grade diamonds for its visibility of inclusion with naked eye. When inclusions are not visible with naked or untrained eye, we call it E1 which is almost 100% Eye Clean.
When some of the inclusions are barely visible with naked eye, we call it E2 or 80% Eye Clean.
When inclusions are visible with naked eye, we call it E3 or No Eye Clean.
