Uriel (Archangel)

Uriel is often referred to as the fourth archangel. The name Uriel can mean "the Light of God" or "the Fire of God."
Uriel's aura is said to be a pale yellow in colour, and Amber would be his stone.
Uriel stands for prophecy and wisdom. He represents the qualities of Devotional Worship, Ministration and Peace, Ideas and intellectual guidance, divine guidance, inspiration, claircognizance, and inner knowledge.

Note that in traditional exegesis the archangels Uriel and Ariel are considered to be one and the same, while most esoteric literature treats them as two separate archangels.
