Commentaar:
Adamite is a classical fluorescent mineral since the discovery in 1946 of large esthetical fluorescent samples in the Ojuela Mine (Mexico).
The rarely seen Chinese adamite in limonitic matrix coming from the Dachang Sn-polymetallic ore field, Nandan County, Hechi Prefecture, Guangxi Zhuang Autonomous region looks like Ojuela specimens. The clear gemmy crystals fluoresce bright bluish-white in LW UV and the green cuprian Adamite fluoresces bright green LW. The SW response is similar for both, in a subdued green color. The Adamite is very short lived phosphorescent.
Cupro- and manganoan-adamite are also sometime fluorescent but usually not as bright as pure adamite..
