The Mazarin diamond specifically identified as sold in 1887 was Le Grand Mazarin , a 19.07-carat pale pink diamond from the French Crown Jewels. It was sold at the famous French Crown Jewels auction in May 1887 and later resurfaced at Christie’s in 2017.

What the record says

  • Le Grand Mazarin was part of the French Crown Jewels sale in 1887.
  • It had previously been in royal collections associated with Cardinal Mazarin and the French kings.
  • A later account notes that it was bought by FrĂ©dĂ©ric Boucheron at that auction.

Why the wording can be confusing

The term “Mazarin diamonds” can refer broadly to the historic group of diamonds linked to Cardinal Mazarin, but the sources available here single out Le Grand Mazarin as the one explicitly documented as sold in 1887.

If you want the full list of the French Crown Jewels sold in that auction, it would need a separate, item-by-item inventory.
