Inclusions in Diamonds
Most diamonds contain inclusions, which can greatly affect stone clarity. Internal inclusions (inclusions inside the diamond) are made during the diamond crystal’s growth billions of years ago. Blemishes (on the diamonds surface) are often caused by the artisans who worked with the stone during the cutting or polishing process. In some cases, external blemishes occur afterwards while being handled by traders and jewelers.
Different types of inclusion affect the price of the diamond. Some inclusions are more visible than others, while others may even affect the stone’s overall durability. Hence, it is of the utmost importance to know what types of inclusions your diamond contains. Inclusion characteristics are always mentioned in the GIA certificate.
