In Illuminati symbolism, Rhodium is the metal of the moon.

Found on Earth in rare supply, it shines with a silvery white surface that immortalizes the power of this planet’s lunar companion. Even in the darkest times, the moon illuminates humankind and brings harmony to life’s most ancient unity: the hallowed bond between the dark and the Light.

Real Rhodium metal is used to create the silver Rhodium Illuminati Talisman, which is worn as a mark of Illuminati affiliation by members who have dedicated their lives to the advancement of the human species.
