Blue Heart Diamond Ring

This 30.62 carat heart-shaped, brilliant cut blue diamond was faceted by French jeweler Atanik Eknayan of Paris in 1909-1910. The stone was purchased by the French jeweler, Pierre Cartier in 1910. Cartier then sold it to a Mrs. Unzue of Argentina in a lily-of-the-valley brooch in 1910. It was next acquired by Van Cleef & Arpels in 1953 and sold to a German baron in the form of a pendant. In 1959, it was purchased by Harry Winston who mounted it in its present platinum ring setting, surrounded by 35 round brilliant cut white diamonds. The Gemological Institute of America (GIA) graded the Blue Heart as a natural fancy deep blue diamond with a clarity grade of VS-2. Mrs. Marjorie Merriweather Post generously gifted the Blue Heart Diamond to the National Gem Collection in 1964.
