A pic viewed from the end might help. Emerald is in the Beryl family. Beryl is a 6 sided crystal. Tourmaline is a rather rounded, 3 sided crystal.

It looks like an emerald, but it would have to be looked at closely by a cutter to determine its value.

Nice piece!..................HH

Beryl can be separated from tourmaline by hardness
Beryl runs to a hardness of 8 on a Mohs scale and tourmaline is at 7 to 7 1/2.

Both are classified as Cyclosilicates
Both are Hexagonal in crystal habit.

A gem cutter of jeweler would be able to help,
if you don't have a good mineralogist handy.

Yes it's an emerald but to check for cutability place in on a strong light and see if there are any imperfection's in the center.
