It can be harmful as well as unsightly because, if your water isn't well-buffered, it can cause big pH fluctuations, as well as release other nasties. "metallic-looking minerals like pyrite (fool's gold) or galena need to be avoided. metallic-looking minerals are usually sulfides, but can also be arsenides, selenides or antimonides. They can oxidize under water, releasing acids, potentially toxic metals and other solutes." Taken from http://fins.actwin.com/aquatic-plants/month.200107/msg00298.html.
