Sapphire occurrence in gneissic granite with lots of mica. Dudley Blauwet (2014) writes: "On my Dari Map, it is shown as Hazrat Saeed, about 50-60 km down the Kokcha from Sar-e-Sang, below Jurm. In Urdu, Saeed would be spelled Sayed. When pronounced to me in Dari, the "H" was very soft and came across as Azrat."

Formula: Al2O3
Reference: Moore, T.P.,Woodside, R.M.W. (2014): The Sar-e-Sang Lapis Mines, Kuran Wa Munjan district, Badakhshan Province, Afghanistan. Mineralogical Record 45 (3), 280-336.
Dravite
Formula: Na(Mg3)Al6(Si6O18)(BO3)3(OH)3(OH)
Habit: trigonal prism
Colour: blue
Description: Ian Nicastro notes at https://www.mindat.org/forum.php?read,105,414229,414229,page=1#msg-414229 that "Dravite and Dravite-Uvite attributed to Koksha Valley are likely from Hazrat Saeed specifically, since multiple specimens attributed to Koksha Valley have turned up with both sapphire and blue dravite in the same mica matrix. And Hazrat Saeed appears to be the only Sapphire source in Koksha Valley."
