the ring itself:

the symbols:

from what i found out by myself:
first square: it's 18 carat (750)
second square: the Ibis bird means it's made out of gold
third square: it was created between 1975-1976 ? i was told that this ring is ~100 years old. is it possible that the same sign was used earlier? here is a table with the dates: http://www.books.google.com/books?id=Ll ... C&pg=PA199 does the table mean that prior 1940 the Egyptians used latin alphabet - A, B, C , D for the date?
also do the dots mean something too, or if i missed anything else here?
thanks in advance.
