Circa 1938 - 1957, The Zircon color was only produced for 3 years (1936 - 1939) so it falls right at the beginning of Whirlpool production (approximately 1 year). Of all the Heisey colors Zircon is one of the most collectible & sought after. The Goblet is 5-3/4" (H), 2-7/8" (W) at the rim and 2-5/8" (W) at the round scalloped foot. It holds approximately 9 ounces and the condition is excellent without chips or cracks. Note - there are 6 available but they are priced each. If multiples are ordered, savings on shipping/insurance will be refunded after shipping.
