Suggestions/Inspiration for naming an incrediblely rare stone?

Basically this stone, would allow somebody to preform a ritual (currently all i got for the ritual is that it's performed at midnight), and let's you "Ascend" into a higher being.So from Human to Angel, Angel to Archangel, and finally Archangel to God. Basically, Ascension allows a person to live longer and get stronger/faster and more durable, (quick note Godhood would make you Inmortal and Invincable, unless another God intervenes). One last thing is the stone is tied to my worlds central religion, which is very loosely inspired by the Abrahamic faiths.
