GIA’s clarity scale has 11 potential grades for clarity. Clarity refers to a diamond's appearance when examined under 10X magnification, specifically assessing the presence, size, number and location of internal inclusions and external blemishes.

If you’re looking for a round brilliant diamond without any visible inclusions, diamonds from Flawless (F) down to VVS₂ don’t have any inclusions visible to the unaided eye. However, it is possible for minor surface blemishes to appear on Internally Flawless grades.

If you’re looking for a diamond without visible inclusions that is also relatively affordable, consider diamonds in the VS₁, VS₂ and SI₁ grades. All diamonds in the VS₁ grade have inclusions that would be difficult to see with the naked eye. Most diamonds in the VS₂ grade have inclusions that would be difficult to see with the naked eye, and some diamonds in the SI₁ grade have inclusions that would be difficult to see with the naked eye. The latter two categories can provide incredible value.

Because diamonds in the VS₂ and SI₁ grades cost less, finding a diamond with no inclusions visible to the naked eye can be an incredible value.

Be careful about going down to the I category to save money, however, as their inclusions are obvious and some of these diamonds can appear dull or may be more fragile.
