indicolite help

hey guys
i was wondering if you could help me with something
last week, i went to the annual rock and mineral show in wollongong, while i was there i came across and bought a piece of indicolite from pakistan from one stand. After a week of looking at it, something tells me its not indicolite but aquamarine or probably of anther stone
the pictures i took are of a really bad quality and I'm sorry about that
that crystal looks like quartz crystals, and has no grooves in the surface of the crystal like a normal tourmaline crystal.
any help would be appreciated
thank you :)

You need to get a photo down along the c-axis - the long direction. If it is a fairly even hexagon, it will be aquamarine. If the sides sort of bulge out, it will be tourmaline.

what do you mean by bulge out
um
its more hexagonal in shape, so does that mean its actually an aquamarine

It exist Pakistani tourmaline in this colour but with this poor photos is indistinguishable from aquamarine. Try to make more pictures in focus using macro lens, some from c axis direction as pointed by David. If you can not, attempts to describe crystal shape: lateral prisma faces, termination, bevels, etc.

Beryl has a six fold symmetry on the c-axis (long direction). The angles between adjacent faces will be equal. Tourmaline is trigonal and there will be two different angles between adjacent faces (creating a sort of bowed out triangle).
