Clarity of diamonds
The clarity of a diamond describes the number and type of inclusions or imperfections present within it.
The purer a diamond is, the higher its value. Most diamonds have very small inclusions. The fewer and smaller these inclusions are, the better the light can pass through the stone.

| VS1/VS2 | very slightly included | smaller inclusions difficult to slightly easier to see under 10x magnification |
| SI1/SI2/SI3 | slightly included | small inclusions easy to very easy to see under 10x magnification |
