Siblings to two of this year's French classic winners are among 325 yearlings consigned for a truly star-studded Arqana August Yearling Sale.
On the 20th anniversary of the creation of the Deauville highlights, which takes place Aug. 15-17, Ecurie des Monceaux will be offering a Siyouni half brother to the brilliant unbeaten Diamond Necklace (Lot 128). The filly, who was purchased for €1.7 mares at the same sale in 2024, has clinched the French trilogy of Prix Marcel Boussac (G1), Poule d'Essai Des Pouliches (G1), and Prix de Diane (G1) for Coolmore and Aidan O'Brien.
The colt is out of Monceaux blue hen Prudenzia, making him a half sibling of the 2013 Irish Oaks (G1) winner Chicquita and world-traveler Magic Wand. Amo Racing bought her daughter by Night of Thunder for €3 million at last year's sale. Overall, Prudenzia's progeny have generated an eye-watering €14,895,000 in Arqana August sale receipts.
The same auction will see Haras du Cadran offer a Kodiac half sister to the same team's Prix du Jockey Club (G1) hero Constitution River (287), who is from the group 1 family of Wonderful Tonight.
Other Arqana August graduates to have kept its name flying high lately have been Balantina, heroine of the 2025 Breeders' Cup Juvenile Fillies Turf (G1T), and Opera Ballo, winner of the Jebel Hatta (G1T), who finished third in the Queen Anne Stakes (G1) at Royal Ascot.
No fewer than 18 siblings to group 1 winners are set to go through the Deauville ring in those three days. The full catalog can be viewed online.
