The Gemological Institute of America is boldly going where it has never gone before — the automated grading of diamond clarity. The GIA announced a collaboration with IBM to develop an artificial intelligence system for evaluating diamond clarity.
The lab is currently testing the system on stones weighing 4 carats and below, with plans to expand it and begin sending out stones that have been evaluated using artificial intelligence in 2021.
Pritesh Patel, senior vice president and chief operating officer of the GIA, said AI clarity grading works by feeding datasets — the GIA has thousands of stones in its reference collection that are used as standards.
Once the training is complete, the program will continue to follow this training and the GIA can add more data over a period of time so that the intelligence of the system will continue to grow.
Automated assessment is nothing new to the GIA. It has been part of the GIA since its inception since the son of the Lab’s founder, Robert Shipley Sr., Robert Jr., helped the lab develop a tool to support visual color grading in 1940.
