TitleAdamite with limonite
DescriptionAdamite, Zn2(AsO4)(OH) (zinc arsenate hydroxide), is a favorite among collectors of fluorescent minerals because of its consistent bright green fluorescence under short and long UV light. It also makes a wonderful mineral specimen in ordinary light. The typical lime green color of its adamantine (high luster) crystals set on top of its commonly associated red limonite matrix make specimens particularly attractive. Limonite is not a true mineral, but a mixture of similar hydrated iron oxide minerals.
