Can anyone please help identify this tea set and pattern? It is a beautiful teal bluish green pattern. The diamond mark is only on one saucer. The number on all pieces is 1592. The saucers, cups and sugar bowl have 1592 with 3 dots under the 92 in an inverted triangle. The tray has the 1592 marking but with 5 dots shown like a 5 would be on a set of dice. All pieces except the saucer with the stamp have a gold x on the bottom. One of the cups has a 6 under the 1592. Looking for the manufacturer, date produced, name of pattern and worth.
Thanks in advance!
