Understanding Diamond Cut
Diamond cut is one of the most important factors affecting a diamond’s beauty and brilliance. Unlike shape, which refers to the diamond’s outline, cut determines how well a diamond reflects light.
A well-cut diamond allows light to enter through the top, reflect internally, and return through the crown, creating exceptional sparkle and fire. Poorly cut diamonds may appear dull even when they have excellent color and clarity.
Diamond Cut Grades

- Good
- Fair
- Poor
Higher cut grades generally produce greater brilliance and visual appeal.
Why Cut Matters
A diamond with an excellent cut often appears larger, brighter, and more attractive than diamonds with lower cut grades. Cut quality directly impacts light performance and overall value.
