In a 1974 letter written to Mr. Dietrich, Kenneth L. Van Atten, then Executive Vice President of Cartier, states 'The natural star ruby in which you are interested weighs 16.16 carats and the lovely color and clear star make it a stone of rare beauty. The ruby was originally sold by Cartier in the 1920s to Mr. E. H. Augustus. Recently it was re-purchased by us from this important estate along with various other items of jewelry. Gem quality rubies have always been scarce but since World War II they have become even more so, adding extra value and prestige to the one who can count such a ruby among his possessions. I am of the opinion that the star ruby is a Burma ruby.'
The semi-translucent ruby is a deep purplish red color; a shade deeper in color than indicated by the printed catalogue illustration. Exhibits a distinct 6-rayed star with very slightly wavy legs. The mounting is heavy and well made, with nice detail in workmanship. In good condition. Signed Cartier and numbered 89265 on the inner gallery. Fitted with an inner sizing band. Box signed Cartier.
