Diamonds in Earth’s oldest zircons are nothing but laboratory contamination

In 2007 and 2008, two research papers reported in the journal Nature that a suite of zircons from the Jack Hills included diamonds. Now geologists at the University of California, Riverside have discovered using electron microscopy that the diamonds in the Jack Hills of western Australia are not diamonds but broken fragments of a diamond-polishing compound that got embedded when the zircon specimen was prepared for analysis by the authors of the Nature papers.
