noun

A 138.7 carat ruby, known for its great color and well-defined star pattern

The Rosser Reeves Ruby is a 138.7 carat ruby from Sri Lanka well known for its star pattern and rich color. It is named after the famous advertising mogul, Rosser Reeves, who purchased and donated the gem to the Smithsonian Institute in 1965. The stone was more than 140 carats when first purchased at auction, but was polished and refined before it was donated to the Smithsonian to reach its current weight. The stone can still be seen today at the museum, along with several of the world’s most famous and largest gemstones.
