As summerized from Melody's Love is In the Earth:

Augite can be used to enhance the understanding of metamorphisis in one's life. Augite can be used to ameliorate the more trying transformations. Purple Augite can be useful for providing guidance during spiritual growth. Brown Augite useful for clearing oneself of "muddy" emotional, spiritual, or physical issues. Streaked black Augite for healing painful transformations while allowing one to remain grounded and centered in reality.

All Augite can be used to ameliorate problems associated with calcium deficiencies especially with elixirs.

I hope this helps some. ;-)
