Corundum crystallizes in the trigonal system and has a Mohs hardness of 9, second only to diamond among standard reference minerals; the blue coloration associated with sapphire commonly results from trace elements within the crystal structure.\u003c\/p\u003e\u003ch4\u003eTraditional \u0026amp; Metaphysical Associations\u003c\/h4\u003e\u003cp\u003eIn crystal and spiritual traditions, sapphire is associated with wisdom, integrity, focused intention, and contemplative practice.
