What is an “ideal cut” diamond?
In order to achieve the maximum play of light, a diamond must be ideal cut. The ideal cut is a mathematical formula for cutting diamonds to precise angles and proportions to gain the optimum reflection and refraction of light.
You may choose to economise on colour, clarity or size, but to ensure that you have the most brilliant diamond possible, you should never compromise on cut.
What makes the “ideal cut” so important?
When a diamond is ideally cut, light rays from all sides are bent towards the centre of the stone and are reflected back through the top in a blaze of light. If a diamond isn’t ideally cut, light will “leak out” through the side or bottom of the stone causing a loss of brilliance. The ideal cut guarantees you a spectacular balance of brilliance, sparkle and fire.
When you buy a non-ideal cut diamond, you may pay more for extra weight. But the extra depth or thickness can actually detract from the brilliance of your diamond. All diamonds have brilliance, but an ideal cut diamond will offer the maximum play of light and sparkle.
Because more of the original rough diamond must be sacrificed to achieve an ideal cut, only a small percentage of diamonds are cut this way.
