Color:
Yellow, Dark yellow, Dark red, Orange.
Density:
5.43 - 5.7, Average = 5.56
Diaphaneity:
Translucent to subtranslucent
Fracture:
Sub Conchoidal - Fractures developed in brittle materials characterized by semi-curving surfaces.
Habit:
Disseminated - Occurs in small, distinct particles dispersed in matrix.
Habit:
Granular - Generally occurs as anhedral to subhedral crystals in matrix.
CI meas= -0.136 (Poor) - where the CI = (1-KPDmeas/KC) CI calc= -0.117 (Poor) - where the CI = (1-KPDcalc/KC)
KPDcalc= 0.1804,KPDmeas= 0.1835,KC= 0.1614 Ncalc = 1.88 - 1.92
