Fluorescence and time-resolved fluorescence measurements in dominican ambers have been reported. These studies show that the "blue" variety reveals an intense fluorescence emission in the visible wavelength region, between 430 and 530 nm, with spectral features which are typical of aromatic hydrocarbons. On the contrary, the dominican "red" and "yellow" amber varieties have a much weaker and featureless emission, although still do have a certain fluorescence. The process in blue amber is surprisingly similar to phosphor. Has diferent variarity size , weight , dimensions
