A brilliant cut is a round cut diamond with 57 facets and its prescribed proportions. Because the round brilliant cut diamond is the most wanted cut, it is extremely important to execute the polishing of this cut with utmost care and attention to achieve optimal brilliance and light reflection. A brilliant is generally used in a diamond engagement ring in a traditional solitaire setting, with or without sparkling side stones. When light enters the brilliant cut diamond, the light refraction creates a unique image in every single corner of the diamond. It is the most common choice for a golden engagement ring or for brilliant earrings. When a woman turns her head while wearing brilliant earrings, the diamonds will sparkle due to incidence of light.
