    Diamond is the hardest known natural material on Earth. Due to it's hardness it is cut using a laser. Laser cutting means each cut is the smoothest, which ensures a greater amount of light reflection due to a smoother surface. The light which enters into it gets reflected from all the angles and thus makes it sparkle.
