I am an online gemology student, from Europe. To get more experience I moved to India. Here I have find some good priced tanzanite and some Sri Lankan sapphires.
They may be your interest too!
I have a Samsung phone only to take pictures, so the focus is not always excellent, also I try my best with the color, but still can't catch the sparkle of the stones, maybe a video would do it.
(I finished the GIA Colored Stone Grading lab in London)
