The position of inclusions can affect the value of a diamond. You may not notice a significant difference between an SI 1 and a SI 2. However, you should consider the number, size, brightness, nature and position of the inclusions.

Some inclusions can be hidden by a mounting, thus having little effect on the beauty of a diamond. An inclusion in the middle or top of a diamond, however, could impact the dispersion of light, sometimes making the diamond less brilliant.
