Heavy Grape, Imperial
Imperial's Heavy Grape pattern is distinguished by a quilted diamond effect around the edge and has a simple fluted back. Shown above left are a chop plate and an eight-inch plate--both highly desirable. The eight-inch plate is seen more frequently than any other shape. Punch sets are hard to find.

At the left is a small bowl in blue--a rare color for Imperial. Note that this is also the rare variant without the quilting.

Dugan made a pattern also called Heavy Grape that has a leaf in the center that does not have the quilting effect. Lenox/Imperial, Fenton and Smith have reproduced this pattern.
