UV fluorescent Lapis Lazuli tumblestones
UV fluorescent Lapis Lazuli tumblestones from Afghanistan, bright blue stones with a hidden side - bright orange and yellow fluorescence under 365nm UV light. This is due to the presence of various fluorescent minerals, particularly Calcite.
The three grades given in this material don't refer to the blue colouration/quality of the stones but rather the level of fluorescence displayed as some are significantly brighter than others.
I test these items with a 365nm Convoy flashlight.
