Which clarity grades are eye-clean?

Most VS1 and VS2 diamonds are eye-clean, and many SI1 (and some SI2) diamonds are too, depending on the size and position of inclusions. Always confirm by viewing the specific stone.

Is an eye-clean diamond worth it?

Yes. Choosing an eye-clean SI or VS diamond instead of a flawless one saves a large amount while looking identical to the naked eye, letting you spend more on cut or carat.

How do I know if a diamond is eye-clean?

View the diamond in person or check a high-resolution photo and the GIA clarity plot. Look for inclusions near the centre of the table, which are more visible than those near the edge.

Quick Answer

What does eye-clean mean for a diamond?

An eye-clean diamond has no inclusions or blemishes visible to the naked eye at a normal viewing distance of about 20-30cm. Many VS1, VS2 and even SI1 diamonds are eye-clean while costing far less than flawless grades. Choosing an eye-clean stone is the smartest way to maximise size and sparkle for your budget.
