Optical Properties of Aurorite
Gladstone-Dale:
CI meas= 0.26 (Poor) - where the CI = (1-KPDmeas/KC) CI calc= 0.244 (Poor) - where the CI = (1-KPDcalc/KC)
KPDcalc= 0.2584,KPDmeas= 0.2532,KC= 0.3419 Ncalc = 2.3 - 2.4
Optical Data:
Biaxial (?), a=2
RL Anisotrophism:
Yellow-gray to brownish gray.
RL Bireflectance:
Strong, cream white to medium black.
