The cut of a diamond significantly impacts its appearance, removing nearly half of the original rough stone.
Among the most important steps in diamond processing is the initial cut.
The traditional round shape remains the most popular, followed closely by oval and princess (square) cuts.
However, modern cutting techniques have introduced a variety of breathtaking new shapes.
The cut determines the diamond’s brilliance by controlling how light is reflected and refracted within it.
Achieving the perfect cut requires meticulous calculations of symmetry and proportions.
This is especially critical for intricate shapes like hearts or trillions (triangles), where the precision of angles, symmetry, and corner cuts must be flawless.
Such craftsmanship not only enhances the beauty but also influences the value of the polished diamond.
While the proportions and symmetry of the cut play a key role in determining a diamond’s worth, they do not replace the importance of the 4C’s.
Special tools are used to assess the cut quality and how well the diamond reflects light, ensuring its brilliance is maximized.
Diamond Cut Quality:
The quality of a diamond’s cut is graded at different levels: Excellent, Very Good, Good, Fair, and Poor. These ratings assess how well the diamond’s proportions and angles reflect light, ultimately determining its brilliance and overall beauty.
Deep Cut Diamonds: When a diamond is cut too deep, it may appear smaller than other diamonds of the same carat weight.
This is because much of its weight is concentrated at the bottom, reducing the visible surface area and impacting its sparkle.
Ideal Cut Diamonds: Diamonds with an ideal cut are perfectly proportioned to maximize light reflection, creating a vibrant and radiant sparkle.
This cut style ensures that the diamond shines brilliantly from every angle.
Shallow Cut Diamonds: A shallow cut causes light to escape from the sides of the diamond instead of being reflected back through the top.
As a result, the diamond appears less brilliant and loses its full potential for sparkle.
