The diamond 3EX cut is the most dazzling. 3EX cut is a perfect diamond cut, which refers to SYMMETRY being EXCELLENT, CUT being EXCELLENT, and POLISH being EXCELLENT. The combination of these three is 3EX. The diamond fire color displayed by 3EX cutting is the best.
Diamond cutting grade
1. Poor Cut (POOR), often abbreviated as P grade
This includes all diamonds that do not meet the general cutting standards, where the cuts are either deep and narrow or shallow and wide, making it easy for light to escape from the edges or bottom.
2. General Cutting (FAIR), often abbreviated as F-grade
A diamond cut with a roughness of 35% is still a high-quality diamond, but the light reflected by a general cut is not as good as that of a G-grade cut.
3. Good cut, often referred to as G-grade
The diamond cut, which represents a roughness of about 25%, reflects most of the light entering the interior of the diamond, making it much cheaper than VG grade.
4. Very Good Cut, often abbreviated as VG Grade
A diamond cut with a roughness of about 15% can reflect the same light as a standard grade cut, but at a slightly lower price.
5. EXCELLENT, often abbreviated as EX grade
Representing a standard that only 3% of top-quality diamonds can meet, this cut almost reflects all the light entering the diamond, creating an elegant and outstanding cut.
