American socialite weds British aristocrat. WWII disrupts their French life. Post-war, they launch jewelry firm from survivors' heirlooms. Business booms but clashes with new era's changes.

Sarah Thompson, an American visiting England, meets and marries William Whitfield, the Duke of Whitfield. They settle in a chateau in France and begin a family. World War II interrupts their happiness and alters their future. After the war, the family helps war survivors by buying their jewelry and eventually opens a jewelry store, which rapidly becomes a success. But conflicts abound as new generations arise and forces from both outside and within threaten the store and the family.—Anonymous
