Vorlanite $(CaU^{6+})O_{4}$ [$Fm\bar{3}m$, a = 5.3647(9) Å, V = 154.40(4) $A^{3}$, Z = 2] was found in larnite pyrometamorphic rocks of the Hatrurim formation at the Jabel Harmun locality, Judean Desert, Palestinian Autonomy. Vorlanite crystals from these larnite rocks are dark-gray with greenish hue in transmitted light. This color in transmitted light is in contrast to dark-red vorlanite [$Fm\bar{3}m$, a = 5.3813(2) Å, V = 155.834(10)$A^{3}$, Z = 2] from the type locality Upper Chegem caldera, Northern Caucasus. Heating above 750 $^{o}\textrm{C}$ of dark-gray vorlanite from the Jabel Harmun, as well as dark-red vorlanite from Caucasus, led to formation of yellow trigonal uranate $CaUO_{4}$. The unusual color of vorlanite from Jabel Harmun is assumed to be related to small impurities of tetravalent uranium.
