This large plain colored piece does not look like all the much under normal lighting BUT get it under SHORT Wave UV and the specimen lights up (first two pictures). It also fluoresces under LONG Wave but not as bright ((third picture). There is also very slight daylight fluorescence as can be seen in the fourth picture.
