Diamond cutting is the process of shaping and polishing diamonds to enhance their beauty and brilliance. This involves carefully removing material from the rough diamond to create facets, which are flat surfaces that reflect light. The skill of a diamond cutter is crucial, as the angles and proportions of these facets determine how well the diamond sparkles. The most common cutting styles include the round brilliant cut, which maximizes light reflection, and the princess cut, known for its square shape. Each cut requires specific techniques and tools, ensuring that the final product showcases the diamond's natural qualities while meeting the preferences of buyers.
