Several different types of cut are used on gemstones to make them more beautiful. One of them, in particular, is the diamond cut which has numerous facets that would give them an exceptional brilliance.
The resultant shape of purple gemstones that is formed would resemble the structure of a cone and would allow maximum light from the top of the diamond.
The round brilliant cut would be preferred when the crystal has the shape of an octahedron because this would allow two stones to be cut from the very same crystal. The oddly shaped crystals would be cut in the form of a fancy cut, rather than the round brilliant cut.
There are various reasons for the preference of the brilliant-cut over the other cuts:
The brilliant piece is very popular because of its beautiful look and there is a reason to believe that you could find different gemstones of various shapes and sizes in the brilliant-cut. It is one of the most preferred types of cutting gemstone and that means more options for you.
The brilliant cutting is to be used to cut loose gemstones if the highest brilliance and fire are to be achieved.
Due to a phenomenon, the light that refracts into the diamond can come out of it only after several reflections inside the diamond, due to the design of the piece. Thus it would seem like it produces its own light and makes it sparkle wonderfully.
The brilliant cutting is also quite good to be used as a solitaire. This is because people would often come to prefer the round shape, that is offered by the brilliant-cut.
