Adamite is a favorite among collectors of fluorescent minerals because of its consistent bright green fluorescence under
short wave and long wave UV light. It also makes a wonderful mineral specimen in normal daylight or artificial light. The
typical yellow to green color of its high luster Adamite crystals that form on top of normal brick red-orange limonite matrix
make these specimens really attractive.

Adamite is a Zinc Arsenate Hydroxide mineral. It is a mineral that typically occurs in the oxidized or weathered zone
above zinc ore occurrences. Pure Adamite is colorless, but usually it possesses a yellow color due to Iron mixed in the
mineral structure. A green color may also occur and is due to copper mixed in the mineral structure. The yellow to green
colored crystals with their distinctive lime green fluorescence make Adamite a favorite among mineral collectors.
Adamite is found in Mapimi, Mexico; Greece; in the USA in California and Utah.
Adamite occurs as a secondary mineral in the oxidized zone of zinc and arsenic bearing hydrothermal mineral deposits.
It occurs in association with Smithsonite, Hemimorphite, Olivenite, Calcite, Quartz, Iron and Manganese oxides.
