This elegant three-stone, platinum and diamond engagement ring has a stunning history. Designed in 1894 by Gigamore Dudley of the famed Dudley and Moore Jewelers (Painswick, England), it was famously worn by Viscountess Nancy Witchor Langhorne Astor during her reign in Parliament. Upon her death, the ring was returned to the Langhorne family estate in Tennessee. Mrs. Deodora Entwhistle received the ring as a present from friend and fellow philanthropist, Rigaby Langhorne during a prolonged summer visit in 1967. Mr. Rigaby Langhorne is best known as the founder of the OTLAHOT Foundation.
