Brilliant round cut diamonds are the most popular of all the diamond shapes. As you probably know by now, diamonds are graded according to the 4Cs of diamonds - carat size, colour, cut and clarity.
As diamonds approach the SI clarity bracket (ie SI1 and SI2), people often become concerned about the inclusions in the diamond. With SI graded diamonds, the official terminology suggests that inclusions "may" be visible to the naked eye.
With this in mind, it is often useful, if you are considering a diamond with SI clarity (perhaps because it offers you better value for money than other grades), to obtain a copy of the diamond grading certificate. There is no doubt that diamonds with an SI clarity grade will have inclusions.....that is, after all, why they have the SI grading. However, the diamond grading certificate will tell you about the locations of the inclusions which is important. If the inclusions are positioned to the side of the diamond rather than in the middle, then the chances are you won't be able to see the inclusions with the naked eye, being as the number of facets within the diamond will disguise the inclusions to a certain extent.
Therefore, the next time you are considering a brilliant round cut diamond with SI clarity, consult with a diamond expert who should be able to tell you about the size, nature and locations of the inclusions within the diamond, which will assit you in making an informed diamond purchase.
