Hematite (Specularite) is the mineral form of iron(III) oxide. Hematite is a mineral, colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite).

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate. The red staining comes from iron oxide impurities. Calcite is a common constituent of sedimentary rocks, limestone in particular, much of which is formed from the shells of dead marine organisms. Approximately 10% of sedimentary rock is limestone.Calcite is the primary mineral in metamorphic marble. It also occurs as a vein mineral in deposits from hot springs, and it occurs in caverns as stalactites and stalagmites.

Garnets have been used since the Bronze Age for gemstones and abrasives. Garnet is said to be good worn next to the skin and for conditions such as arthritis, pancreatitis and varicose veins.
