-Would it be useful to add this as a reference for the Dravite from Koksha Valley?
-Would it be worth it on the Hazrat Saeed page to mention that the 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.
-Only a totally different note... multiple sapphire crystals of specimen quality from Hazrat Saeed I have examined have a weakly radioactive mineral on/in them. Peter Slootweg and I hypothesized that it could be Zircon or a Microlite Group mineral. The mineral giving the radiation has a corroded looking shape and a grey color and is likely mistaken for books of mica at a quick glance. Not every sapphire has it, but quite a few do. This is the first time I have ever seen sapphire specimens with detectable radioactive inclusions. I haven't had a chance to have these analyzed.
Hello Ian, my two cents-yes to both
Andrew 
The more information the better. 
Oddly the marble from Sar-e-Sang is slightly hot with a couple of hundred counts per minute above background. It doesn't seem associated with any specific mineral.
The Dravite from the Kokcha Valley is yellow green and from a white schist occurrence https://www.mindat.org/loc-253959.html. There may be more than one such occurrence, but there were no blue dravites here.
I'll add this to Hazrat Saeed https://www.mindat.org/loc-255436.html Please check it. Interesting to hear Rob, I've never been able to handle any large pieces of marble matrix from there.
Thanks for your help, and I agree with you that those are two distinctly different dravite sources. Rob-Ian, do either of you have any details on pargasite found in Koksha ?
Thanks
Andrew The min rec article on volume 45, may-june, 2014 has one paragraph on them. It mentions brownish crystals of them. I've not handled any from there personally. Hi Rob, are the light green pargasite crystals in pinkish-violet calcite/marble from this area?

Basaltic sapphires from Vietnam contain, among other minerals, pyrochlore and baddeleyite.
Corundums/rubies from both basalts and marble may contain zircons.
Van Long, P., Quang Vinh, H., Garnier, V., Giuliani, G., Ohnenstetter, D., Lhomme, T., Schwarz, D., Fallick, A.E., Dubessy, J. and Trong Trinh, P. (2004): Gem corundum deposits in Vietnam. Journal of Gemmology, 29, 129-142. 
Just visual data but there are some differences between the mica of blue dravite and sapphire samples, both supposedly from Hazrat Saeed, that I tend to doubt they are from the same place. The mica accompanying blue dravite has a blue hue while that in the sapphire is more yellowish. In my blue dravite sample, that I received labeled just "Badakhshan", some mica areas are deep pink, a color never seen in sapphire mica matrix.
Also the response to UV is quite different. In Dravite samples the mica has a slighly yellowish fluorescence while that one with the sapphires is absolutely inert. And maybe the most significative difference: corundum from Hazrat Saeed is fluorescent in white o soft blue zones while that present in dravite samples is not.
I don't know if the photos have grasped the differences...
I've interestingly never come across baddeleyite on a corundum that gave me a radioactive signal. Pyrochlore is a great idea, I'll see if I can get this tested soon. I feel if it was zircon I'd get a uv response, but I don't.
I've actually come across large sapphires on both what I refer to as the 'greenish' mica matrix and the more 'brownish' mica matrix from Koksha Valley area. I've gotten detectable radiation signals from sapphires on both types of matrix 2-3x above baseline. I agree that the Dravite definitely does seem to occur only on the green/bluish mica matrix. I imagine there are probably multiple tunnels at Hazrat Saeed and so maybe the differences in what we are seeing might be attributed to variability in chemistry across the deposit.
I've never seen pink tinged mica from there until now, but I found another photo online besides your specimen. I also have to wonder if acid cleaning could be playing a role in things, as mica from local pegs where I live will often look green after acid cleaning, but brownish gold before. Although you mention the greenish/bluish mica on the Dravite matrix giving yellow fluorescence, I do not observe that with SW UV on my Dravite specimens green matrix. I do see fluorescence in the white areas of the sapphire just like you mentioned.
Until someone treks out to the remote sapphire area I doubt we will know what's actually going on. Hmmm.... I never had a dravite and no longer have a corundum from Kokcha Valley, so I'm really in the dark here. Josรฉ has pointed out some real differences in the micas. Maybe an EDS might shed some light on this? I remember the Fe staining on the mica with corundum and it might be as Ian says that the dravite mica might be less weathered. This is the real problem with these localities. Until some one with some geological training gets to them we will just be guessing. What to do? 
I still feel that these specimens originate from te same locality or area. Maybe a different zone in the rock produces the green mica with the dravite. Jose mentioned a great difference in reaction under UV. I have several of these specimens from both finds and under SWUV and LWUV these specimens give the same reaction under my lights. Secondly most of the green mica specimens with dravite show parts with brown mica of he same color and hue as the specimens with the big sapphires (photo). Also the presence of tiny yellow grains with slight radioactivity in both paragenesis pull these specimens together in my opinion.
Jose is right that the sapphires in the green mica do not show any fluorescence and the big sapphires show a bright orange fluorescence at the white tips of the crystals. Many of these specimens have been oiled that may alter their reaction under UV. The only thing that bothers me, is that I have never seen the two types offered for sale at once, as from the same locality. Even in big lots of the big sapphire in brown mica material I have never encountered a green dravite bearing specimen and vice versa. Also the pink mica is something I have never seen myself. my initial thought it was staining from the pink toiletpaper these specimens are often wrapped in.
Like Rob says, until somebody goes up there and collects the facts it's one big educated guess.
I'm completely clueless after seeing Peter's last photo with greenish and brownish mica together!
To add more complexity to this matter, let me show the backside and a lateral view of my dravite sample.
Some zones of the mica have deep pink color:

Weird. I wish we could get a Raman spec on the pink stuff. This is such a strange deposit.
I assume that's a mineral and it's not a dye... i.e. if you put that in water, the pink doesn't leach out. I only ask because I have received Hackmanite crystals that were dyed before from the region. Fractured translucent crystals had dye placed in the fracture and then were glued back together. 
I think Ian has a point here. The pink colour is so strong and the other mica in the sample is pale greenish that it seems to be too good to be true? And the strong red-purplish fluorescence of the pink mica makes one wonder....
Raman - if you hit the right spots - should possibly bring up organic dye compound peaks as well...or else sensible spectra related to natural pink mica...
Cheers,
Joel There is a pink Phlogopite at Ladjuar Medan as well as pink sodalite. They are mm sized spots and are definately not from pink toilet paper wrapping that got wet. Today I sent the specimen to a friend who can do a LIBS of the different micas, will post the results when done. My fooly guess for the pink mica: muscovite with manganese. Here they are the LIBS spectra made by Adolf Cortel. There is a similar metals content in mica from dravite specimen and mica from corundum specimen, which seems to be an argument in favor to think they are from the same locality or at least from localities not far one from another.
The high Mg content do not fit with muscovite. Maybe phlogopite?
Pink mica in my dravite specimen gives also a similar spectra. After checking metals content without find significative differences between clear and fuchsia micas, it was found that fuchsia color is soluble in alcohol, which indicates a probable artificial dyed. What a bad surprise!
Comments will be welcome. Thank you.
Here comes the fluorescence spectra of the dye, maybe somebody can identify it.
Wow thank you for having all of that interesting analysis done! Sorry about the dye... My theory is that dealers were trying to dye the mica to make it look like lepidolite. At least it looks like it will come off easily. That's interesting the mica is not muscovite. 
I ran across this thread as a "similar discussion". For those still interested, I've now microprobed a specimen of the blue "fluor-dravite", along with the corundum and mica (and other minor phases). I posted the results at the following thread (not far from the end: 21 March 2020 08:13 UTC), where it had also been discussed:
