Sapphires

crystalvaults.com tells us:

The sapphire "is a stone of wisdom and royalty, of prophecy and Divine favor. It is forever associated with sacred things and considered the gem of gems, a jewel steeped in the history and lore of nearly every religion. To the ancient and medieval world, Sapphire of heavenly blue signified the height of celestial hope and faith, and was believed to bring protection, good fortune and spiritual insight. It was a symbol of power and strength, but also of kindness and wise judgment. 

"Today Sapphire is still a Stone of Wisdom, a royal stone of learning, mental acuity and psychic activation, a seeker after spiritual truth. Its pure Blue Ray brings order and healing to the mind, lending strength and focus, and an ability to see beneath surface appearances to underlying truths and to utilize that knowledge. It stimulates the Throat and Third Eye Chakras, allowing one to access deeper levels of consciousness in order to gain a fuller understanding of self. Associated with the planet Saturn, Blue Sapphire embraces order, structure, and self-discipline, and is ideal for accomplishing goals and manifesting ideas into form. Sapphire’s power to transmute negative thoughts and energy also makes it highly effective for earth and chakra healing. [Hall, 253][Ahsian, 340][Simmons, 339]"
