Hi Seven Oranges,
as another member pointed out, there is some other member in Bahrain and you could also try Dr. Tom Stern as well as looking for in India. Many of the gulf pearls went to India and now some of the owners are selling them again.
Then you could look up auction houses as well! Just be prepared to pay premium prices!
The Necklace is lovely and the design of the ring does look rather modern! How nice to know your greatgrandmother had it!
