Shattuckite is a moderately valuable and rare copper silicate mineral, prized by collectors and jewelry makers for its vibrant sky-blue, indigo, and greenish-blue patterns. It heavily stimulates and aligns the Throat (for honest expression) and Third Eye (for inner vision) chakras, while extending upward to the Crown and downward to the Heart. It was first discovered in 1915 in the copper mines of Bisbee, Arizona, specifically the Shattuck Mine (hence the name). It is a secondary mineral that forms from the alteration of other secondary minerals.
