Good friends (R.I.P.) of ours in Ireland gave this piece to us many years ago.
Belleek China owns Donegal China. Here is a description.
"Each piece of Donegal China requires the attention of no less than 21 pairs of highly trained hands during the production process and only first quality products are backstamped with the company logo. The skill and commitment of the craftsmen is evident in the flawless beauty of each piece."
