Yes, that could be it. If you are comfortable with the ID then maybe it would be good to move the pictures. If you want confirmation on the Plant ID forum, go for it. I do not have any experience with Vera Higgins but the pictures look close to your plant.
I know Opalina from having seen it here and there for years. It is reasonably common and unusually large for this kind of hybrid. My own plant is 7 or 8 years old (having been beheaded and restarted once during that period).
Two good references if you are curious for more info...
