There is widespread agreement that the diamond industry has a need for a widely accepted and reliable cut grading system. Continual improvement of luxury goods that compete with diamonds has led to a growth in their share of consumers dollars. An advanced, but easily communicated, grading system will give the diamond industry a much needed impetus, but not only by way of creating better consumer confidence. The industry will gain more freedom in diamond cutting and this can lead to the creation of more beautiful diamonds and better profits.
Developing such a system that is acceptable and beneficial to all parties, is a complex task involving the optics of the stone as well as human taste and physiology. The implementation of such systems will require new approaches, technology and devices, as well as good communication and throughout all sectors of the industry.
Our presentation is devoted to the explanation of one methodology of diamond cut grading. In this methodology we avoid grading cut based on proportions and similar parameters. We will base our system on the optical responses of each diamond; this approach will allow the development of a universal system that will apply to all diamond shapes, and other gemstones.
Further more, this proposed system will lead to differentiation of market segments and of consumers groups.
Cut quality influences diamond beauty and value but the complexity of grading cut results in diamonds that are more and less beautiful falling into the same cell of a pricelist. To combat this, a lot of effort today goes into branding diamonds. Producing consistently beautiful new cuts can add value to branding efforts. However labs do not currently rate round diamond beauty, let alone compare and evaluate the beauty of different fancy shapes or new cuts. The short comings of current lab evaluation methods, via parameters (proportions and angles), reduces the economic need for diamond cutters to create more beautiful cuts.
Adding to the limitations of lab grading systems is the high cost of rough for empirical testing and experimentation. Development of our approach would also result in computer aided design technology to develop new cuts.
Is it possible that diamonds will be designed that are superior to diamonds considered as excellent or ideal today?
