BRILLIANT CUT DIAMOND

A brilliant cut is a diamond or gemstone that has been cut with numerous facets in order to exhibit brilliance, more commonly known as sparkle.
This brilliance is as a result of the light returning throughout the cone shape of the stone itself. Think about a diamond like a window – a well cut window will let the most light enter through the window.
A well cut diamond should do the same, and the light should bounce off facets of the diamond, resulting in the iconic sparkly appearance of a diamond ring.
When we think of a classic, iconic engagement ring-it’s typically a round cut diamond solitaire ring that comes straight to mind.
Representing almost 75% of diamonds sold in the market, round brilliant cut is the most popular shape.
