In terms of diamond value, how do inclusions compare to blemishes?

Inclusions and blemishes both affect a diamond's value, but inclusions generally have a more significant impact on the stone's overall quality and value. Inclusions are internal features, such as crystals, clouds, or feathers, that are embedded within the diamond. They affect not only the clarity grade of the diamond but also its structural integrity and brilliance. Since clarity is one of the key factors in determining a diamond's value—alongside cut, color, and carat weight—any significant inclusions can noticeably decrease the diamond's market price.

On the other hand, blemishes are external features, like scratches or nicks, that can also affect the diamond's appearance but typically have a less severe effect on its value compared to inclusions. Blemishes can often be polished out, while inclusions are permanent characteristics of the diamond. Therefore, when assessing the impact on value, inclusions usually outweigh blemishes, making them the more significant factor in the diamond's overall assessment. This is why the correct answer highlights the greater importance of inclusions compared to blemishes.
