I’ll sift through hundreds of thousands of diamonds online and help you find the perfect stone for you and your budget. Unlike the other sites, I’m not looking to sell you anything – my advice is objective and in your best interest. You have nothing to lose.

After you’ve had a chance to read my general clarity review and my article Truth About Diamond Clarity, now we can take this opportunity to evaluate the diamond SI2 clarity grade specifically. As mentioned in previous articles, the diamond SI2 clarity grade is very easily noticeable with a 10x loupe, and is sometimes visible to the naked eye. The diamond SI2 clarity grade is distinguished from the diamond SI1 clarity grade simply how much area the inclusion covers. As you can see in the sample pictures included here, there is a very wide range of possible qualities within the diamond SI2 clarity grade.
Diamond SI2 Misconceptions
Many people often make the mistake of not purchasing a Diamond SI2 clarity grade stone because they are afraid that the inclusion (blemish) will be noticeable to the naked eye. If you are buying blindly, without a picture (such as from Blue Nile or other similar online shop), then there is some wisdom to that. The diamond in the picture on the bottom-left will most likely have an eye-visible blemish. But the other two stones will not.
This is one of the reasons why I recommend people buy from James Allen – they offer high quality photos of their inventory with their virtual loupe tool. This allows you to buy a diamond with an SI2 clarity grade with confidence that it will be completely clean to the naked eye. Buying a Diamond SI2 over a Diamond SI1 or even Diamond VS2 will allow you to either save significant money, or buy a larger diamond with the same budget.

Hi Paul. They’re all very nice. If JA can confirm that this one is eye clean, then I think it’s your best bet:
