Cut refers to the shape of the finished diamond. While nature determines the colour, carat-weight and clarity of a diamond, only a skilled craftsman can determine the cut, displaying the fire, sparkle and beauty of the diamond. When a diamond is cut to perfect proportions – thus not too deep nor too shallow – light will reflect inside the stone and disperse through the top of the stone, making it seem to radiate from within. A badly proportioned or badly cut diamond can appear watery and dull. There are various different diamond cuts, catering to almost any taste and preference.
