Unusual Yellow OPAL Cased Glass VASE with Gilding, Enameling and Gemstones

We don't usually see this bright OPAL Yellow Color in Cased Glass, so today when I saw it at a Flea Market, I wanted to bring it home and find out more about it. It is cased with an inner layer of yellow glass with a clear layer outside. It measures 3 1/2" tall by 2 1/2" in diameter and has a very Victorian Ribboned Gold Bough highlighted with Ruby & Emerald stones (real?) and Rich enameling on the Ribbon. On the back of it there is a gilded bough with enameling. The rim is flat and polished and the under-base is flat with a concave center. Any ideas on who made this little vase? Thanks all, BOB
