No Data


Some very small crystals (a few mm) of achroïte from Elba Island are fluorescing the normal blue color under UV at 380nm and an unusual bright yellow fluorescence under UV at 306nm.
Activator is unknown, but the achroïte contain Mn and a very high amount of Mg (15-20%) but many non fluorescent tourmaline contain as much Mg.
Some very small crystals of achroïte included in quartz are practically only detectable by their strong yellow fluorescence.
Other colored tourmaline (pink, yellow and green) from Elba show sometimes a very weak yellow fluorescence.
