The Use of Laser and X-ray Scanning to Create a Model of the Historic Koh-i-Noor Diamond

mold in December 2007 suggests that at least one lead model was also made, but there is no documentation to confirm this. The two plaster casts are the only replicas known to have been made from the original stone (a cubic zirconia [CZ] replica has been cut based on one of these plaster forms, as described in Hatleberg, 2006, but no details as to the specific techniques used were provided in that report). One of the plaster casts is on permanent display at the museum, but the other was analyzed for this study using a combination of photographic techniques and laser and X-ray scanning technologies to create a computer model of the original Koh-i-Noor. This model was used to determine the alignment of the historic stone within the original diamond crystal (and test one theory of its origin), analyze the THE USE OF LASER AND X-RAY SCANNING TO CREATE A MODEL OF THE HISTORIC KOH-I-NOOR DIAMOND
