The Mouna Diamond weighs 112.53 carats and is VS1 clarity.
When it was submitted to the GIA on November 9th, 1995, they stated that up until this date it was the largest Fancy Intense Yellow diamond that they had ever graded.
The cushion-shaped stone is 26 mm in diameter set in a baguette-cut mount by Bulgari, which with it the diamond has a height of 36 mm. It was sold by Christie’s in Geneva on November 16th, 1998, lot 161, and fetched $3,258,000 (about $28,773 per carat).
It was owned by Mouna Ayoub. Her former husband must be a man of some considerable wealth: apparently she once told him that she enjoyed jogging, and the next day a team of workmen began building her a running track around the perimeter of their estate in Saudi Arabia. The gem was part of her divorce settlement – along with a rather impressive collection of other items.
