Evidence from the paper
The bulk modulus obtained on a similar crystal (from the same bulk sample) with lower-pressure single-crystal data to ~9 GPa (Jacobsen et al., 2002) is 158.4 (±0.4) GPa with K' = 5.5 (1), somewhat higher than the current study.

note
Difference attributed to limited pressure range or different pressure scales (quartz volume versus ruby fluorescence)
