Your mineral does look like it may be green Beryl. Beryl is not an uncommon mineral. It is found in many colors some of which are considered gem stones. Morganite (pink), Heliodor (gold), Aquamarine (blue green) and Emerald are the most desirable color groups of Beryl and if of sufficient quality and size can bring a good price in the gemstone market. They are all the same mineral but different colors.
Emerald is a particular rare green color of Beryl. I have traded in Emeralds for more than 40 years. Your mineral in no way approaches the color profile of Emerald.
