This interesting opaque glass, called Blue Marble was introduced in 1970 and remained in the line through 1973. The color was produced by adding opal into a pot of opaque blue glass to produce the distinctive swirls of white. This beautiful Bud Vase measures 2 1/2" at the base and 10 1/4" high, and is in excellent condition no nicks, chips, cracks or scratches.
