In one of the easiest wins of the week, Diamond Necklace (St Mark's Basilica) made light of Thursday's G1 Qatar Nassau Stakes at Goodwood.Having joined a select group to complete the French trio of Marcel Boussac, Poule d'Essai des Pouliches and Prix de Diane, the 4-6 favourite showed she is far from finished tackling the older fillies and mares for the first time in this 10-furlong feature. Always cruising under Ryan Moore, the unbeaten €1.7million 2024 Arqana Deauville August topper swooped on last year's Prix de l'Opera winner Friendly Soul (Kingman) approaching the furlong pole en route to a 2 3/4-length success. See The Fire (Sea The Stars) could get no closer than five lengths further back in third as she placed in the race for the third year.Moore was equalling the record of six wins in this. “She was very comfortable and that was the best she's felt,” he said of Aidan O'Brien's seventh Nassau and 14th Group 1 winner of 2026. “She's obviously thriving and improving and it was very easy really. She was a little bit idle in front and is a proper racing machine. She travels with loads of pace and enthusiasm and has a real good turn of foot like her father.” SPARKLING dazzles in the @Qatar_Racing Nassau Stakes.@Goodwood_Races | @Ballydoyle | @coolmorestud pic.twitter.com/yZJciCikkD— Racing TV (@RacingTV) July 30, 2026The post ‘A Proper Racing Machine’: Diamond Necklace Smooth For Moore In The Nassau appeared first on TDN | Thoroughbred Daily News | Horse Racing News, Results and Video | Thoroughbred Breeding and Auctions.
