Hessonite garnet ("Gomeda" in Sanskrit) is the Jyotish gem related to Rahu (Moon's ascending node), which is mainly an elemental and instinctual entity. When badly positioned, this "shadow planet" is characterized by insatiable worldly recognitions and desires together with sense gratification. Wearing a hessonite of at least 2 carats is said to bring success, wealth and notoriety in society, increase life span and good fortune. Hessonite can be substituted with orange zircon.
