This is a delicate Belleek, Ireland sugar bowl or sugar basin made 1955-1965 with the 2nd green mark.
The Belleek creamer is in the Lotus Luster pattern or shape with a lovely molded design of flowers called Lotus.
The sugar basin or bowl measures 2.2 inches high by 3.25 inches in diameter and is in good used vintage condition with no chips but there is a very tight hairline crack in the base that I had difficulty seeing which is reflected in the price.
It is absolutely beautiful, and would still work for sugar. A wonderful addition to the tea table.
