Clarity
Clarity refers to a diamond’s internal features, (inclusions), and surface characteristics, (blemishes), that are visible when it is viewed under 10x magnification. The more imperfections a diamond has, the lower its resale value will be. Flawless diamonds are very rare and can be extremely valuable. Clarity is graded on a scale ranging from Flawless to I3, (I3 is the last clarity grade considered acceptable for use in jewelry). When selling your diamond, it is helpful to have some understanding of its clarity. There are many different types of inclusions. They may appear as black specks, cleavages or white lines within the diamond.


How can you determine your diamond’s clarity?
If your diamond is of significant size, (.50cts plus), you should be able to get some idea of its clarity grade even without a 10x magnification tool. I1 and lower clarity grade means that the diamond contains inclusions which can be seen easily with the naked eye. If you are able to quickly locate inclusions when looking over your diamond it is most likely in the I1 or lower grades. If you notice inclusions but they are not easily seen when looking over the diamond, it is probably in the SI1-2 range. If your diamond is in the VS2 or better range, you should not be able to locate the inclusion with the untrained, naked eye.
Can the location of an inclusion affect my diamond’s resale value?
The location of a diamond’s inclusion can be a factor when a buyer is determining the value of your diamond. The reason for this is that an inclusion in the center of a diamond is much more difficult for a setter to hide in jewelry then one which is off to the side and can be hidden under prongs. The location of a diamond’s inclusion should not affect its clarity grade, but it can affect its potential marketability for a buyer.
