This is a cased English satin art glass vase dating to the 19th century, circa 1885.
The interior glass is opal white. The outer glass is ruby at the neck, shading to darker pink and shading to pale pink, and it is over a diamond air trap pattern. On the outside are applied gold Coralene beads, outlining the diamonds and branching up towards the mouth.
The rim of the mouth is round with the residue of gold enamel trim, the gold being mostly worn.
The bottom has a distinct indented round polished pontil, with one area of roughness that I point to with a red arrow and which appears to be a burst air bubble.
There is one burst air bubble on the side of the vase that I point to in another photo with a red arrow. The gold Coralene has a little bit of dirt on it due to age.
The underside is hand enameled with the numbers and letters of "24/319/18 cm" followed by "700."
There are no chips, nicks or cracks.
