Limonite is a mineral which has a brown (sometimes banded) earthy appearance and texture. It is also one of the 2 major sources of iron ore (the other being hematite) and is sometimes referred as ‘brown hemattie’. The mineral specimens we offer are fairly dense as expected and can often contain varying coloured bands of brown to yellow. Formed from the hydration of hematite and magnetite, limonite has historically been used as a colour pigment in paint. These particular samples come from the famous Cooper Peedy deposit in Australia and so may contain small occurrences of blue opal, our samples here are avialable in lots of 1 kilograms and comes supplied in a polythene bag with an information card, the sizes of mineral specimens inside vary betweeb 20 mm to 80 mm.
