Further Details
This sapphire was originally purchased by David Rockefeller in 1943 from Raymond Yard. The sapphire was in a platinum mounting, set with two half-moon diamonds. The ring was an estate purchase made by Mr. Yard who listed it as a 'Cashmere Sapphire.' In 1952 the sapphire was reset into its current mounting.
