The Belleek mark If there is no mark then it is not genuine. An Irish Wolfhound with its head turned back to face a Round Tower (believed to be Devenish Round Tower on Devenish Island in Lower Lough Erne). To the right of the Tower is an Irish harp. Below, two sprigs of shamrock border the ends of the banner carrying the word "BELLEEK".

FIRST PERIOD BLACK MARK 1863 - 1890
Early pieces of parian leaving the pottery were either impressed with the word "BELLEEK" or BELLEEK, CO FERMANAGH. Others were impressed and marked with the Belleek 1st period mark. The colour of the mark during this period was predominantly black but other colours were sometimes used, example red, blue, orange, green and brown. Some pieces of Belleek also carry the British Patent Office registration mark, which gives the date of registration, not the date of manufacture.

SECOND BLACK MARK 1891 - 1926
Belleek changed its mark to comply with the McKinley Tariff Act of 1891, requiring imports to the USA to specify the country of origin. A second banner was added below the first mark, carrying the words CO FERMANAGH, IRELAND.

THIRD BLACK MARK 1926 - 1946
A stamp with the words "DEANTA IN EIRINN"
(made in Ireland) and the registered trademark number
0857 was added below the banner.

FIRST GREEN or FOURTH MARK 1946 - 1955
The mark remained the same but had a colour change.

SECOND GREEN or FIFTH MARK 1955 - 1965
To identify that the Belleek mark was registered in the USA the letter "R" within a circle was added above the banner.
