Circa 1931 - 1956 Diane is a pattern that enjoyed a long production history as well as coming in many of Cambridge's most popular and collectible colors. This is the first sterling trimmed plate I have seen. Most sterling trimmed pieces include Rose Point or Chantilly. It is 9-5/8" (W) at the rim with a 3/4" sterling decorated rim. The polished base is 4-1/2" (W) and the plate stands approximately 1" (H) at the rim. Condition is excellent without chips, cracks or wear to the sterling.
