The show decides whether or not gem types are the same as real life gem types or specific stones, although I personally love the idea of there being a big gem type being "beryl", it seems the creators have chosen each type of beryl to be it's own gem type.

However, it could just be that, in a similar fashion to Peridots, Era 1 Beryls are taller than Era 2 Beryls, and Emerald here is Era 1 while Aquamarine is Era 2. And although unlikely, It could also be that Emerald is short and child-like, but has a different face shape than Aquamarine, much like we've seen other gems that are of the same type having different face shapes.
