I'm not an expert on opaline glass, but I think that this may be opaline. It's a cobalt blue with gold accents. The red flower design is a transfer, I believe. It could be part of a fireplace mantel set, but once again, I'm not sure.
The vase stands approximately 15.25 inches tall and 8 inches wide at the golden handles. Please look at the pictures for description. The gold is messy at the bottom, and the vase is approximately 1/8 of an inch shorter on one side.
