Find-diamonds computer program

Partition Enterprises has been working together withrepparttar De Beers company andrepparttar 124183 University of Queensland to develop a program that calibratesrepparttar 124184 density separator x-ray sorting machines more accurately, thus maximizerepparttar 124185 diamond yield. Partition will showcase their products atrepparttar 124186 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 „onrepparttar 124187 cards”, otherwiserepparttar 124188 supply of diamonds may become dangerously scarce for that company. That is whyrepparttar 124189 offered diamonds will be eventually purchased regardless of their quality –repparttar 124190 pack diamonds can be argued on but they are very rarely rejected, asrepparttar 124191 sightholder cannot afford to lose its status and breakrepparttar 124192 relationship with De Beers Diamond Trading Company, relation that is essential for business. In Japan,repparttar 124193 only company appointed as sightholder is Tasaki.

Innovative complementary grading tool

A new feature will be added in grading reports:repparttar 124194 light performance. Althoughrepparttar 124195 concept of measuringrepparttar 124196 light performance of diamonds has been introduced six years ago, this standard of diamond evaluation was never introduced intorepparttar 124197 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 – besidesrepparttar 124198 certification ofrepparttar 124199 4Cs, its light performance will be measured. The specific section inrepparttar 124200 report will containrepparttar 124201 results of diamond analysis under six different lighting angles. The GemEx Light Performance Report makesrepparttar 124202 difference between diamonds with similar 4C characteristics that can differ in brilliance, fire and sparkle. The analysis isrepparttar 124203 result of a patented spectrophotometer technology based onrepparttar 124204 computerized BrillianceScope that measures diamonds’ brilliance, fire and sparkle, providing a powerful tool forrepparttar 124205 cutting, sales, buying and marketing of fine diamonds.

New Technology in Diamond Properties Analysis

Written by Laura Ciocan


Continued from page 1

Diamonds’ appearance differ when observed in diffuse/ambient light conditions. Strong light conditions emphasize fire and scintillation whereas in softer lightrepparttar optical symmetry is emphasised more.

Unlike BrillianceScope, Isee2 performs its analysis in diffuse light conditions. Diamonds that perform well on Isee2 analysis will look smashing in softer light conditions. Ifrepparttar 124182 diamond is well graded onrepparttar 124183 BrillianceScope it will look stunning in direct light conditions.

This technology facilitatesrepparttar 124184 choice decision by permitting buyers to be convinced ofrepparttar 124185 qualities of a stone all by themselves withoutrepparttar 124186 help of a layman.
