Marvelous jade cased opaline glass. The vase is 6 1/2" tall and exhibits a wonderful translucence when held to the light. The crimped rim shows the delicate cased form. We believe this is Vineland glass, possibly early Durand. It is in excellent condition, no chips or cracks, and the only flaw we can find is one small, faint tooling mark at the base of the neck, almost unnoticeable. A gorgeous piece for the art glass collector.
