Blue Murano Turned-edge Geode Dish: A flat wide rim cased glass define the geode style from Murano. This fine example is in a clear royal-aqua blue and has a well-crafted turned edge rim. It is most likely is from the 1960s. The term “geode” is quite literal: the art glass resembles a geode mineral sample sliced to reveal the jewel tones inside. Very heavy considering it is only five inches across.
