To get a beautiful eye clean diamond online, you would need to look at the images and videos of a lot of diamonds before making your purchase. This is often a much better way to shop than going to a local jeweler who would have you looking at diamonds through a loupe. When you see the images and videos online they are under far more magnification so you can easily see any imperfections. When selecting the center diamond for an engagement ring, you would want to avoid diamonds with inclusions that can be seen through the table the flat area on the top.

Clarity Grading Factors There are five different factors that can have an effect on the clarity of the diamond, these factors are size, nature, number, relief, and location. Size — The larger the inclusion in the diamond, the lower the clarity grade will be. A large inclusion can also have an impact on the durability of the diamond, which is why a lower grade diamond should not be bought. Nature — Nature refers to what type of inclusion it is and takes into consideration the depth of the inclusion.
Inclusions are flaws which penetrate deep within the diamond, whereas blemishes are flaws that do not penetrate the diamond but are instead confined to the surface of the stone. Number — The number of inclusions is important, as the larger the number of inclusions or blemishes, the lower clarity grade of the diamond will be. However, if the inclusions are not visible, it will not have an impact on the overall number rating.
Location — The location refers to the position of the inclusion or blemish in the diamond. The closer the inclusion is to the center of the table, the more effect it will have on the clarity.
This is because it interferes with the way light reflects within the diamond. Inclusions closer to the girdle are difficult to see, but if they are close to the surface they could damage the stone. Relief — Relief is the distinctness of the inclusion when viewed within the diamond. Therefore the greater the relief, the larger the effect on the clarity grade. The Importance of Clarity Going below an SI1 diamond runs the risk of you purchasing a diamond with a visible inclusion, which could affect the overall sparkle and brilliance of the diamond or you purchasing a diamond with an inclusion that might affect the durability of the stone.
Finding an SI1 diamond which is clean to the eye will help you save a significant amount on your budget and you will still be left with a beautiful sparkling diamond that will look gorgeous in any setting. They should always be considered eye-clean to the naked eye. The larger the diamond, the more visible the inclusions. The reason is that they are just cheaper than comparable VS2 diamonds. You have to be careful however. Below on the left we can see an eye clean SI1 diamond and on the right an SI1 diamond that is not eye clean:.
Both diamonds are SI1 diamonds. The one on the left only has traces of haziness that can be viewed with 20x magnification but not with the naked eye! Go and check out the diamond on the right however. You will be able to see if from all angles. You will see that the dark inclusion under the table facet is well visible. It is not only visible under 20x magnification but also if you zoom back to real life size. This is how you can know whether the particular inclusion will be visible to the naked eye or not.
This particular inclusion will therefore be visible in real life as a tiny dark speck. Such a dark speck might mistaken for a speck of dirt but of course you still want to avoid it! This brings us to the main rule for SI1 diamond inclusions: Avoid any larger dark inclusions under the table facet! If the same inclusion had been white the diamond would in all likelihood have been eye clean. I want to demonstrate this to you with another example.
Below you can see two eye clean SI1 diamonds:. If you click on the left diamond you will see that there are some slightly dark clouds under the table. But because these clouds are not really dark in nature but somewhat transparent these cloud inclusions will not be visible! That is one of the most important things to remember about inclusions.
