What is a crown?
The crown of a diamond refers to the upper part of the diamond, which includes the topmost section of the diamond above the girdle (the widest part of the diamond). The crown is an important component of a diamond's overall appearance and value, as it plays a significant role in how the diamond reflects and refracts light.
The angles and placement of the facets on the crown can greatly impact the diamond's brilliance, fire, and scintillation. A well-cut diamond will have a properly proportioned crown that is neither too shallow nor too deep, allowing for maximum light reflection and refraction.
If the crown is too shallow, light will escape from the bottom of the diamond, resulting in a loss of brilliance and fire. If the crown is too deep, light will be trapped within the diamond, making it appear dull and lifeless.
