CUT

CUT

LEVEL:

  • IDEAL
  • EX
  • VG
  • GD
  • FR
  • IDEAL:

    The highest cut standard above the 3EX level has stringent requirements for diamond proportion, polishing and symmetry, ultimately reflecting light perfectly.

  • EX:

    The diamond industry has a high standard for cutting, which allows light to enter the diamond and reflect as much as possible to create a balance between fire and light.

  • VG:

    The measurable fire color is slightly less than the excellent cut diamond, but the price is more affordable, to meet the needs of some consumers on the market.

  • GD:

    There has been a compromise in quality, but it is more common in color diamonds, because the price of colored diamonds is expensive, and weight preservation will be the preferred choice.

  • FR:

    There is a big sacrifice in the quality of diamonds. Generally, low-quality cheap diamonds will adopt such cutting standards, which are relatively rare on the market.
