Auto DIASSORTERTM is jointly developed by Eternity Manufacturing Ltd. and the Hong Kong University of Science and Technology to sort diamonds according to their colour and clarity grading. The system employs the latest technology in image processing that measures the properties of the diamonds based on pictures captured by high resolution cameras. It can handle diamonds with diameter ranging from 0.8mm to 3mm. These diamonds are transported to the sorting system by an automatic feeding device. The fully automatic grading process takes about 6 seconds per stone and the result will show the colour / clarity of the diamond in accordance with the industry standard. With this information, the graded diamond will be delivered to a designated bin as programmed by the operator.The system facilitates the automatic sorting of diamonds in large quantities.
