If you like adventure tales containing historical treasure, then you will love the thriller of the Sancy Diamond. I will not go into the fascinating 600 year history of the one of the most sought after diamonds in the world. It is my intent to simply spark your interest by telling you only one of its many alluring tales.

The Sancy Diamond is pale yellow 55.23ct shield shaped, double rose cut diamond. It derives its name from the French Ambassador to Turkey, Nicholas Harlai, the Seigneur de Sancy, who was an avid gem and jewelry collector in 1570.  (Don’t you just love men like that?)

Pale Yellow 55.23ct Sancy Diamond

During the reign of Henry IV, Sancy was made Minister of Finance. King Henry IV then borrowed the not-yet-known-as The Sancy Diamond to use as collateral to finance only one of the many wars this gemstone has seen. In the days before FedEx, a messenger had to be sent to deliver the diamond to the King.  That messenger never reached the court. He was followed by thieves en route who murdered him in search of the treasure they knew him to be carrying. It would not be an uncommon story if the messenger had run off with the diamond himself, reporting his own murder back to the French court to cover his tracks. Luckily, Sancy believed the messenger was loyal and had a search made for the man… or the man’s body.  When the man was discovered, no diamond-Sancy or otherwise- was found on the messenger.

Nicholas Harlai refused to give up. The search for the Sancy diamond continued over the area where the body was last seen. The King’s men policed the area and the diamond was finally found. Strangely, it just wasn’t found in the area or ON the messenger.

The Sancy diamond was actually found in the messenger’s stomach. The loyal man had swallowed a 55.23ct diamond to prevent the thieves from stealing it!


With a story like that, it’s no wonder that there are entire books written about the Sancy Diamond. Its owners have been beheaded, lost it at the Battle Boyne, and have been deposed. Marie Antoinette, Napoleon Bonaparte and Queen Elizabeth have all had a hand in this diamond’s fascinating tale. It is said to be one of the most cursed diamonds in history.

I encourage you to do your digging into the past and read more about the rest of this diamond’s many bedtime stories.
