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 categories of flaws, namely blemishes and occlusions. Occlusions are cracks or foreign particle in the interior of the stone, while blemishes extend to the surface. While both can weaken diamonds and make them liable to fracture, blemishes are by far the worst in this regard, and also may affect the sparkle more.
Stones found in Nature are very rarely flawless; there are always at least some flaws or blemishes. Sometimes stones are cut to remove these flaws, but the value of the resulting stones may actually be reduced because of an inferior cut or reduction in size, despite the flawless grading now assigned to the diamonds.
Flaws are used to identify stones, just as fingerprints identify people. They are the mark of a natural stone, with very few achieving a flawless grading. So some flaws are certainly to be expected, although too many which may affect the strength and sparkle will naturally reduce the value.
Because they are mostly so small. Stones are checked for flaws using 10X magnification. This makes it easier to see the flaws and compare their size and type with a chart.Some sort of tools is essential to avoid missing any critical flaws.
People wishing to invest in diamonds or simply purchasing diamond jewelry can make a better choice if they are aware of the different factors. A jeweler should have a diamond clarity chart available for customers. Being better informed about the grades helps decide between attractive pieces, although it is the total combination and balance of all factors which is most important.
