Comments:
I personally made a trip to the source of this material in 2011. I got all the way to the village at the foot of Jaljalla mountain, 14 miles from the nearest road, high up in the foothills of the Himalayas.
I was able to acquire a limited number of these very light, open color tourmalines. Both before, and since that moment I have never seen any others like this available. They must have been a very anomalous pocket. 99.999% of the rest of the material coming from this mine, and the several other mines in the same area are dark, root beer colored dravites.
This slice is a super neat open honey color in 2-tones. It's its own kind of watermelon tourmaline slice, with a slightly yellower honey color rind, and a slightly blue-green-ier color in the center.
The gem's inclusions seem to be small, partially re-healed halo inclusions caused by microscopic inclusions of biotite mica, and possibly other things. It all just looks like faint, wispy spider-webby rainbows. It's a neat effect because it isn't incredibly plentiful.
