Find-diamonds computer program
Partition Enterprises has been working together with De Beers company and University of Queensland to develop a program that calibrates density separator x-ray sorting machines more accurately, thus maximize diamond yield. Partition will showcase their products at Electra Mining 2004 Exhibition in Johannesburg.
De Beers sightholders
Sightholder firms have to satisfy various criteria such as a high degree of expertise in valuing rough diamonds, high experience in cutting and polishing. De Beers has 125 sightholders to whom they assure a monthly direct supply of rough diamonds and from whom they collect around $ 600 million. The privilege of being a sightholder company is carefully preserved, as being a sightholder means being „on cards”, otherwise supply of diamonds may become dangerously scarce for that company. That is why offered diamonds will be eventually purchased regardless of their quality – pack diamonds can be argued on but they are very rarely rejected, as sightholder cannot afford to lose its status and break relationship with De Beers Diamond Trading Company, relation that is essential for business. In Japan, only company appointed as sightholder is Tasaki.
Innovative complementary grading tool
A new feature will be added in grading reports: light performance. Although concept of measuring light performance of diamonds has been introduced six years ago, this standard of diamond evaluation was never introduced into grading reports of diamond grading laboratories. GemEx Systems, Inc. of Wisconsin and EGL USA of New York will provide a combined diamond grading report to diamond customers – besides certification of 4Cs, its light performance will be measured. The specific section in report will contain results of diamond analysis under six different lighting angles. The GemEx Light Performance Report makes difference between diamonds with similar 4C characteristics that can differ in brilliance, fire and sparkle. The analysis is result of a patented spectrophotometer technology based on computerized BrillianceScope that measures diamonds’ brilliance, fire and sparkle, providing a powerful tool for cutting, sales, buying and marketing of fine diamonds.
