On the underside of the base, two of the feet have a star, shaped like an asterisk or starfish. The third has the number "5271" on it. The fourth leg has something, but it's hard to make out. Possibly an "L".
The second metal tier, just under the glass, also has a number: 6139.
The inside and outside edges of the arched glass ridges up top are pretty sharp. The edges of the cross hatch pattern around the bowl are less sharp. Maybe not soft enough to be called "rounded", but definitely not as sharp as up top.
