💙Covellite💙 a rare and beautiful copper sulfide mineral. The color of it was so intense and flashy that it initially had me dismissing it as some metallic spray paint, until I inspected further to find more signs of copper sulfides. When I broke a few pieces off, I found tiny veinlets reaching inside the just like little baby roots.
