Currently, I have not been able to identify the pattern or date of manufacture for this Heisey stemmed bowl. However, it is marked with the Heisey diamond H at the base of the bowl near the stem. In fact, it is marked twice on opposite sides, which is very unusual. It has a 6 1/2" diameter bowl and stands 3 1/2" high with a 1" wide black painted trim. The condition is very good with no chips or cracks and only minor manufacturing flaws. Here is a very unusual piece to add to you Heisey collection.
