GIA New Cut Grade System Starts: Jan. 1, 2006!
The Gemological Institute of America (GIA), the world's foremost diamond grading and research laboratory will be issuing its new Diamond Cut Grading System reports on January 1, 2006, for round brilliant cut diamonds, D-to-Z in Color and Flawless-to I-3 in Clarity. GIA's new reports will include a cut grade accompanied by color, clarity, and carat weight.
GIA is also making available its Facetware (TM) cut estimator tool for assessing diamond cut quality. The tool requires user input for total depth, table size, crown angle, pavilion angle, star length, lower-half (lower-girdle facet) length, girdle thickness, and culet size, as well as the diamond's polish and symmetry grades. Available free for use it can be found here: GIA New Cut Grade System For Diamonds
This is an extremely informative and useful tool/tutorial which should be used and read by all consumers.
