 Adamite
A pale green adamite on calcite small cabinet piece from the Ojuela Mine, Mapimi, Durango, Mexico. It's dimorphous with paradamite and highly fluorescent. The fluorescensce is the same hue under both short and long wave UV - it's caused by uranyl impurities. Thanks to Graeber & Himes' table at the 2000 Carnegie Gem & Mineral Show for the specimen! |
|

|
 Adamite var.
Cobaltoadamite
As with cuproadamite, cobaltoadamite (or cobaltian adamite) occurs when cobalt replaces some of the zinc - it, too, is not an accepted mineral; more just a colored variety, though much rarer than cuproadamite. This beautiful rosy-centered small cabinet specimen comes from the 1998 find at Level 6, Mina Ojuela, Mapimi, Durango, Mexico. The (LW) fluorescence is a bright "new-grass" green but stops short (0.5 mm or so) of the crystal faces - interestingly, Manuel Robbins, in "Fluorescence: Gems & Minerals Under Ultraviolet Light", states that "apparently, the purple adamite from Mapimi does not fluoresce". Thanks to Rob Kulakofsky at the Arizona Mineral Company for the specimen and the closeup (larger image, bottom row) images!

 Adamite var.
Cuproadamite
Copper can replace some of the zinc in adamite, making it green and killing the flurorescence. Cuproadamite (cuprian adamite) is not officially recognized as a separate mineral, but it's often marketed as such. Adamite forms a series with olivenite - cuproadamite is midway. This miniature comes from the classic Christiana Mine, Agios Constantinos, Laurion, Attiki, Greece. Thanks to Tom & Vicki Loomis at Dakota Matrix Minerals for the specimen and the image! | |
