Da Vista Agates
Limonite is a form of iron oxide… oddly enough, the same thing that makes up the beautiful red and orange colors in Lake Superior agates. Many collectors choose to remove the Limonite coating by grinding the outer layer off, polishing, or in some cases, cutting the stone in half to reveal the pattern inside.

Limonite
Limonite is an iron ore, containing a hydrated iron (III) oxide-hydroxide mixture in different compositions. It is one of the two major iron ores, the other being hematite - used in the production of iron. It was named by Johann Friedrich Ludwig Hausmann in 1813 after the Greek word for meadow, indicating its common occurrence in lowlands.
