The diamond clarity scale is a system used to grade the clarity of a diamond, which refers to the presence or absence of inclusions and blemishes within the stone. The scale ranges from Flawless (FL) to Included (I3), with several options in between.
Here is a breakdown of the diamond clarity scale:
- FL (Flawless): No inclusions or blemishes are visible under 10x magnification.
- IF (Internally Flawless): No inclusions are visible under 10x magnification, but minor blemishes may be present on the surface.
- VVS (Very Very Slightly Included): Minute inclusions are difficult to detect under 10x magnification.
- VS (Very Slightly Included): Small inclusions are somewhat easy to detect under 10x magnification.
- SI (Slightly Included): Noticeable inclusions are easy to detect under 10x magnification.
- I (Included): Obvious inclusions are easily visible to the naked eye.
It’s worth noting that the clarity of a diamond is not the same even though different platforms represent a similar jewellery piece.
