Cut

The exquisite polished diamonds are dazzling, and every facet embodies the superb skills of the craftsman. When a diamond is illuminated by light, every angle and every facet will affect the total amount of light reflected back to the eye and affect the frontal appearance of the diamond.

The proportion of the diamond determines the performance of the light after entering the diamond. If light enters through the crown and exits through the pavilion, the diamond will appear dim and unattractive. Different proportions and well-polished diamonds can make better use of light, making the overall bright, colorful and sparkling.

 

 

Carefully cut diamonds can highlight their beauty, which is exactly what consumers want to see.

 

Exquisite diamonds exude elegant charm everywhere, mainly because of three optical effects: white light reflection (brightness), color flicker (fire) and the light and dark areas (flash) presented. The pattern refers to the relative size, arrangement and contrast of the light and dark areas formed by reflections from the inside and outside of the diamond. The light and dark areas of the diamond must have enough contrast to form a clear and sharp pattern.

 

As we all know, the diamond industry has long followed a certain proportion of combinations in order to make the light work better and set off the exquisiteness of diamonds. However, in recent years, scientists and researchers from the GIA Research Department and GIA Laboratory have confirmed that a large number of combinations of different proportions can also maximize the brightness and fire of a round brilliant cut diamond.

 

 

Generally speaking, the higher the cut, the brighter the diamond. Under fluorescent lights, the brightness of these diamonds are: (left to right) high, medium, and low.

"Cut" can also refer to the shape of a polished diamond. All shapes except the standard round brilliant are called fancy cuts. They are sometimes referred to as shaped or shaped diamonds. According to different shapes, fancy shapes also have their own names. The most famous fancy cutting styles include marquise, princess, pear, oval, heart and emerald cuts.
