Reply to "Comment on 'Ruby at high pressure. I. Optical line shifts to 156 GPa' "

Abstract

In our paper [Phys. Rev. B 40, 5724 (1989)] we made independent interpretations based on published data, and did not intend to quote Vohra, Vanderborgh, Desgreniers, and Ruoff. We believe that the fluorescence published as evidence for pressures of 460--550 GPa in diamond-anvil-cell experiments was due to ruby. Therefore, claims of 460 and 550 GPa are acceptable to within the accuracy of extrapolations of the ruby pressure scale.
