This cased art glass vase is is not marked. However, I have a similar piece which is marked Caithness. This Scottish glass company (founded 1961) is known around the world for high quality paperweights and art glass. This vase is no exception. The squatty vase is 4" tall. The outside is primarily butterscotch in color with the base having dark blues, a bit of green and white rolling like waves from the sea. Even the butterscotch color has lines like water in a seascape. The inside is cased with white. The vase is in very good condition.
