There's a lot of Ardisia species. We can rule out A. crenata as it has crenate margins.
It could be A. elliptica but without knowing if there's other species which look much the same it's a guess. Flowers might help.

It might help if you can find out which species is widely used as a house plant.

You might end up having to call it simply "Ardisis spp." meaning it can't be determined to species level.
