This is an American glass covered cheese keeper dish with the under plate. The date is circa 1900, or a date range of around 1890 to 1920.
The under plate is 8 ½”. The dome is about 6 ¼” to the top of the finial and about 6” wide at the bottom opening.
The dome is amberina, shading from yellow to a rosy pink red. The knob finial is applied and is clear glass with points, similar to a cut or press process. The underplate is also clear glass to match the knob finial, with a pointed edge. The underside of the rim is similar to the finial with a cut or press processes, except the points are notched so that the plate sits firmly on the table. The underside of the center of the plate has ridged rays. I believe the plate is original to the dome because the dome is a perfect fit and it matches to the finial. The bottom edge of the dome is polished flat and the sides are beveled very slightly. The glass of the dome has a type of inverted square or geometric pattern.
There are no chips or cracks. The inside edge of the bottom of the dome has a few flea bite nicks that can be felt with the fingers and seen with a very good magnifying glass. The camera was not able to take close-up photos of the bites due to the tiny size. Peering down through the top of the knob the glass looks odd but it is how a solid piece of glass will look when applied.
