It is named after Countess Mona von Bismarck, who donated the piece to the Smithsonian in 1967. The sapphire itself was purchased by the Countess in Sri Lanka in 1926. The necklace consists of a single chain of platinum links connected by pairs of round brilliant cut diamonds. The 98.6 carat table cut Bismarck Sapphire is mounted in a pendant at the front of the necklace, surrounded by baguette-cut diamonds.

The DeYoung Red Diamond is one of the largest known natural fancy dark red diamonds. It is a modified round brilliant cut VS-2 diamond of 5.03 carats. The diamond was acquired by S.
