The compote and lid are marked with the H-Diamond. Orange, black and gold decoration on crystal. The compote has a ribbed pattern radiating from the center of the base and the cover. The underplate does not have this pattern.
The underplate is 12" in diameter; the compote is 6-1/2" in diameter and about 4" tall, not including the finial.
The compote pattern of ribbing suggests Heisey #473 Narrow Flute w/ Rim. Some Heisey crystal pieces are decorated with orange, black and gold, presumably from an outside decorator.
