Description: Left to right, sodalite, lazurite, and reverse of sample discussed here, all from Ladjuar Medam, Badakhshan, Afghanistan.
1 - Under halogen lamp
2 - Under UVA
Sodalite turns to dark orange and some small zones of matrix and between crystals have a whitish shine which could be a feldspar.
Central lazurite is inert while attached phlogopite shines in bright orange.
On the discussed specimen supposed anorthite looks bluish white and appear a pale orange fluorescence that could be white sodalite/hackmanite.
3 - Under UVC
Red shines are calcite.
Central lazurite seems have a slight blue fluorescence (as mentioned in papers) and phlogopite shines yellowish white.
There is some more brights that I hesitate to interpret...
