Amelia's Jewel is an Australian Thoroughbred racehorse. Originally from Western Australia, she has raced at the highest level for the entirety of her career, with all of her starts being in Group races or Listed races.^[1]

She is the daughter of French racehorse Siyouni.^[2][3] In February 2022, Amelia's Jewel had her first trial at the Lark Hill Thoroughbred Training Complex, ridden by Patrick Carbery. She is one of the few racehorses to make their racing debut in a Listed race, winning the Supremacy Stakes at Ascot Racecourse by over two lengths on 5 March 2022.^[4] Following two more dominant wins in the Group 3 Gimcrack Stakes^[3] and the Group 2 Karrakatta Plate,^[3] by a combined margin of over five lengths, she was rested for 29 weeks. Trainer Simon Miller then announced her intended return date to be at the Pinnacles Racing Carnival later that year.^[3]

She resumed racing with a victory in the Listed Belgravia Stakes on October 22, followed by her first career defeat two weeks later in the Burgess Queen Stakes on Melbourne Cup day, finishing second.^[5] On 3 December 2022, she recorded her biggest win to date with a victory in the newly established Group 1 Northerly Stakes.^[6] She was then rested for 17 weeks.

Amelia's Jewel resumed racing on April 1, 2023, in the Group 3 Roma Cup, winning by a length. With another Group win, the three-year-old filly was backed into favoritism for the first running of The Quokka two weeks later.^[7][8]

She started the race slowly, as she is known to do, dropping right back to last place before running on late at the 100-meter mark to draw level with leader Overpass in a photo finish, with the latter winning by a nose.^[9] Following her second defeat, she was once again rested, with trainer Simon Miller stating his intentions to target some of the bigger races in the eastern states, namely the Golden Eagle.^[10]

Following her spell and two trials, Amelia's Jewel was sent to Melbourne in September 2023.^[11] Her first race in the new city was the Group 2 Let's Elope Stakes, where, ridden by Damian Lane, she faced quality opposition including Wrote To Arataki and Pride Of Jenni. In typical fashion she started slowly, settling last, before running on strongly to record another Group race victory.^[12] She would win the Group 2 W H Stocks Stakes at Moonee Valley Racecourse two weeks later, beating Pride Of Jenni again and breaking the 1600m track record at Moonee Valley.^[13] Her next start was in the Group 1 Toorak Handicap at Caulfield Racecourse, starting as the short-priced favorite. In her at the time worst career start, she finished ninth and was subsequently ruled out of a run in the Cox Plate.^[14] Amelia's next race was in the $10,000,000 Golden Eagle at Rosehill Gardens Racecourse, starting as the favorite. She finished 11th in what was her last race of the year.^[15] She was awarded the Racehorse of the Year title at the WA Thoroughbred Racing Awards in August 2023.^[16]

In January 2024, owner Peter Walsh announced Amelia's Jewel would be permanently relocated to Sydney and trained by Annabel Neasham.^[17]

Amelia's Jewel has a distinctive racing style, often settling at the back of the field in the early stages of a race, before producing strong finishes with a "devastating turn of foot".^[18]
