Well, if that's a fitting for a handle sticking out to the left then it looks very much like a silent butler.

Assuming the glass is a replacement and the gem an addition...

The “handle” on the box looks to be about an inch or inch and a half long. Compare that to silent butlers that all have handles that are several inches long.

I see what you’re saying, the proportions are very similar if that actually was a fitting for a handle. But, would you want to see cigarette butts, crumbs and such? What was in the round bezel originally if not glass?
