Waterford cut glass has had an illustrious history and they have created some wonderful cut glass items, and I suspect that often it is their name that might first come to mind when thinking of an origin for such pieces. My opinion is that these are quite likely from Stuart, and certainly much of their glass was unmarked - especially over the past quarter of a century.
regarding the decoration - we tend to use the description cutting when there are deep incisions (mitres) in the glass - these are polished to remove obvious signs of the grinding wheel, so that the entire decoration appears transparent.
Wheel engraving is far less deep, and created with grit and copper wheels, and the opaque textured finish is left like yours as part of the decorative design. However, both forms of decoration do indeed cut into the glass.
