The birth of O.E. Cut diamond and historical background
The art of cutting diamond started in 15th century. Between 18th and 19th century, the technique to increase the brilliancy evolved. By the late 19th century, the foundation for excellent cut was established.
Hundred years has past, throughout the time of evolution, technologies allowed us to give birth to O.E. cut, which increased the brilliancy to the highest level ever. In this 21st century, it is the best cut for people to see the beauty of diamonds.
Feature of the O.E. Cut diamond
Brilliancy, scintillation, and dispersion are the points to evaluate the diamond's value among gemologists.
Although, the O.E. cut diamond has an ordinary 58 faceted round diamond, it has stronger brilliancy, scintillation, and dispersion than the same 58 faceted excellent cut.
That is why the O.E. cut diamonds are attracting gemologists attention.

The difference is quite obvious!
Look at the difference between the picture of the O.E. cut and the Triple excellent cut. It is easy to see how strong the brilliancy is. Also, the back shot of the O.E. cut has turned yellow caused by the strong prism effect. This is led by the study and analysis of optical technology.
Picture on the right shows the laser reflecting from the bottom to the face up. Red dot shows the laser reflecting causing the diamond to shine. The O.E. cut diamond has 450 points and excellent cut has 240 points. As you can see, the O.E. cut diamond has higher brilliancy.
Since the brilliancy, scintillation and diamonds are not only seen in the center, it looks bigger than it actually is. At the same time, the O.E. cut diamond has a larger area than excellent cut diamond.

The grading system that allows us to judge its value by the beauty of the diamond.

The variation of the O.E. Cut diamond
O.E. Rainbow Cut
The O.E. rainbow is caused by transformation of 58 faceted brilliant cut into spiral reflection. The cut maximize dispersion causing the diamond to shine in rainbow color.
O.E. Princess Cut
The Princess cut is known to have delicate impression for its small and fine reflections. The O.E. princess cut may change the impression of delicate image for shining 2 to 2.5times the ordinary princess cut
O.E. melee diamond
The diamond less than 0.1ct is called melee diamond. With advanced technology we put in, you can see a perfect heart shape even in 0.03ct melee. For O.E. cut melee,
not only the diameter is larger, circumference has high brilliancy so the diamond look bigger. (Also, the angles are to cut diamonds,) if used in paves,
harmony of brilliancy and color allows it to shine in higher level. The fancy shaped O.E. cut is in plan for merchandise.
