Short summary
In this work we have applied the elastic geobarometry approach to a Chinese diamond in order to determine the depth of formation of an olivine-bearing diamond. Together with the temperature of residence at which the diamond resided in the mantle, we were able to discover that the diamond was formed at about 190 km depth. Beyond the geological meaning of our results, this work could be a reference paper for future works on Chinese diamonds using elastic geobarometry.
