Once again quoting from the museum fact sheet:
"Blue Ridge Chandelier – Inspired by the adjacent Tiffany Christ Resurrection Window, Blue Ridge Chandelier is presented in the McGlothlin Wing and can be seen prominently from the exterior boulevard window. Functioning as the centerpiece of the exhibition, the chandelier measures over 18’ high, and is composed of 1,135 turquoise, clear and gold glass elements."
