Visiting Investigator Steve Richardson of the University of Cape Town, South Africa, arrived this week for a three-month visit to work with Steve Shirey and Rick Carlson on several natural diamond dating projects. Richardson is joined by one of his students, Karen Smit, who will be visiting DTM for a month, cutting and polishing diamond plates from a suite of Ellendale diamonds from Western Australia. Richardson and his DTM colleagues will be investigating a range of periodotitic and eclogitic diamonds from areas on the Kaapvaal Craton, including Venetia, Premier, and Letseng.
