James Hamlin reaches 174 GPa in October 2007!
Here's
what James' Lu sample (blue oval) looked like at 174 GPa
(diamond anvil has 7 degree bevel
from 350 to 180 microns diameter. The dark ring in the middle marks
where the
concave culet edges are nearly
touching, preventing further buildup of
pressure on the sample).
Narelle Hillier reaches 209 GPa in March 2011!
