Atlantic Jewel (foaled 26 December 2008 at Vinery Stud in Australia) is an Australian Thoroughbred racehorse. Sired by champion sire Fastnet Rock, and raced by Coolmore, Atlantic Jewel was trained by Melbourne's Mark Kavanagh. She has currently won nine of her ten starts, including three Group One races. Her dominant victory at her eighth start in the Memsie Stakes, after a long injury break, confirmed her standing as Australia's best racehorse.
Purchased by Coolmore for $320,000 at the Gold Coast yearling sale, Atlantic Jewel is sired by Coolmore's champion sire Fastnet Rock and by the Zabeel mare Regard. Fastnet Rock himself was a great racehorse, winning the Lightning Stakes and Oakleigh Plate, winning over $1.7 million. As well as being a success in his racing, Fastnet Rock has sired many winners including Mosheen, Lone Rock, Wanted, Sea Siren, Foxwedge, and many others. Atlantic Jewels' dam Regard, was an un-raced mare by the Great Zabeel. Atlantic Jewel is her first foal to race. Her second was the group one filly Commanding Jewel by Commands, making her 3/4 sister to Atlantic Jewel. Commanding Jewel herself won the 1000 Guineas a year later, giving her dam Regard back-to-back wins in the 1000 Guineas.
She was considered as a top contender in the 2011 Spring Carnival, when she defeated her rivals in the 1000 Guineas at Caulfield by three lengths, beating home four-time group one winner Mosheen.
She made her racing début as a three-year-old at Geelong on 23 August 2011. Running over 1,100 metres (1,200 yd), with Stephen Baster, Atlantic Jewel won easily by 1.3 lengths. At her next start, she stepped up to Saturday class and won by just under a length with jockey Michael Rodd easing her up. Winning another race over 1,400 metres (1,500 yd) by 2.8 lengths, Atlantic Jewel's next start would be a test for her, stepping up to group one level. The 1000 Guineas over 1,600 metres would see her against multiple group one winner Mosheen, and stakes winners Hallowell Belle and others. Ridden by Michael Rodd, Atlantic Jewel proved she was a serious contender in the spring, by winning her first Group One by three lengths, winning at a price of $1.70. Atlantic jewel continued onto the Wakeful Stakes, a lead up to the VRC Oaks. Starting at a price of $1.26, Atlantic Jewel seemed to relish the step up to 2,000 metres (2,200 yd), and surpassed her rivals by seven lengths. Atlantic Jewel would start a short priced favourite in the Oaks, but injury ruled her out of the rest of the spring.
