Among the 4Cs, Cut has the single greatest influence on a diamond's visual beauty. While color and clarity are inherent to the rough crystal, cut represents human artistry—unlocking the stone's inner brilliance, fire, and sparkle.
The Three Pillars of Light Performance
- Brilliance: The pure white light reflected back to the viewer's eyes from the diamond's internal and external surfaces.
- Fire: The optical dispersion of white light into vivid, dancing spectral rainbow flashes.
- Scintillation: The captivating pattern of sparkle and dynamic contrasts created when the stone moves in the light.
Diamond Cut Grading Scale
| Cut Grade | Light Return | CHOW HENG FOOK Standards |
|---|---|---|
| Ideal / Excellent | Maximum brilliance and fire; reflects nearly all light entering the crown back to the eye. | Our Gold Standard: Featured across CHOW HENG FOOK center diamonds. |
| Very Good | Captures almost as much brilliance as an Excellent cut with superb everyday value. | Exceptional balance of quality and budget. |
| Good | Reflects a majority of light, though slight proportions allow some light leakage. | Budget-friendly option. |
| Fair / Poor | Light leaks out the pavilion or sides, leaving the diamond looking dark and dull. | Not curated by CHOW HENG FOOK. |
Why Cut Matters Most
Even a diamond with flawless clarity and pure colorless grading will appear dull if poorly cut. An Excellent cut ensures maximum optical presence, making the diamond look brighter, larger, and significantly more breathtaking.
