How to Identify 10 Red and Pink Minerals - thoughtco.com

Jun 22, 2019· Here are some rules of thumb about red minerals: 99 times out of 100, a deep red, transparent mineral is a garnet, and 99 times out of 100, a red or orange sedimentary rock owes its color to microscopic grains of the iron oxide minerals hematite and goethite. A transparent mineral that's pale red is a clear mineral that owes its color to impurities.
