Visit James Turrell's Three Gems in the Osher Sculpture Garden during its optimal viewing time, around sunset. Open 5–8:45 pm.
In 2014, artist James Turrell (b. 1943) contacted the Museums to review Three Gems, a site-specific “skyspace” located in a grass-covered hill in the Osher Sculpture Garden. The work was approaching its tenth anniversary at the de Young, having been installed during the opening of the new building in 2005.
