| Covellite occurs as thin, tabular, hexagonal plates, but more usually it forms in a massive, foliated habit. It is indigo-blue in colour, often tinged with purple irridescence. Covellite is an opaque mineral, and has a submetallic to dull lustre. It occurs in the parts of copper veins that have been altered - often by secondary enrichment, due to fluids seeping through the vein. Hardness: 1 1/2 - 2 | |
