Mineral colour

Orange minerals
Goethite There are hundreds of orange minerals. Many of them contain iron. Do you know what happens when you leave a lump of iron out in the rain? Think of a rusty bicycle! 'Rust' occurs naturally too, as an iron mineral called goethite. Goethite, like rust, is orangy-brown.

Quartz is found in many different colours. The word 'citrine' comes from the same word as 'citrus' - like the oranges and tangerines you eat at lunch. Other minerals that can be orange include heulandite, zircon, topaz and even diamonds.
