Cutting is an important factor that affects the quality of moissanite drill in its classification. It determines the flash, brightness and fire color of the moissanite. Cushion cutting was developed about 200 years ago, and it was not until the early 20th century that it became the most popular diamond cutter for engagement rings. After many improvements, the current effect is a combination of classical cushion shaped appearance and modern bright fire colors. A relatively new change of cushion cutting is the change of fire color, which has a row of additional sections to produce an incomparably flashing "ice breaking" effect.
