There are four factors which determine the value of diamonds. Of them all, clarity, which indicates the number and size of flaws, is possibly the hardest to evaluate. In attempting to arrive at an accurate grading for this factor, a diamond clarity chart is an essential aid, even for the most experienced in the field.
There are two important types of flaws which determine value. These are inclusions and blemishes. Inclusions are cracks or foreign material embedded in the stone and blemishes are on the surface. Blemishes are more serious, as they are more likely to weaken a stone and make it likely to split at that point.
Very few naturally-occurring diamonds achieve a flawless grading, with no blemishes or occlusions present. Sometimes stones are cut so as to eliminate flaws, but this practice can result in an overall lower value, as the size (carats) and cut may be harmed. While flawless is an excellent grading, the overall balance of the different factors is also important.

While they do affect the value of stones adversely, a few inclusions are no great detriment. Large clouds can affect the sparkle, but flaws are useful in distinguishing between stones.
