The horse operates most comfortably at Class 4, which sits in the middle tier of British racing — not the glamour events, but not the bottom rung either. At that level, City Of Diamonds has won 2 from 5, which works out to 40%. Win 2 races in every 5 at any level and trainers take notice. It suggests a horse that genuinely belongs at that grade rather than one scraping by.
Donald McCain trains City Of Diamonds from his yard in Cholmondeley, Cheshire — a well-established operation that has sent out 55 winners already this season, so this is a stable that knows how to get horses to perform. Brian Hughes, one of the most respected jockeys in the north of England, has partnered the horse in 7 of its 11 races, winning once together — 1 from 7, or around 14%. That's not a headline figure, but the partnership has clearly been trusted to develop.
The career arc is worth following. City Of Diamonds got off the mark at Stratford-on-Avon in July 2025 and then added a second win at Musselburgh in November — two very different tracks, which suggests the horse is adaptable rather than a one-trick specialist. Musselburgh, on the east coast of Scotland, and Stratford, in the Midlands, are about as far apart geographically as you can get in British jump racing, and winning at both is a decent sign of genuine ability rather than course-specific quirks.
The recent form — a fall or unseated rider somewhere in the last six runs, plus a couple of sixth-place finishes — shows the horse has had its rough patches, as most do. But with the yard in good form and a horse that has already shown it can win at its preferred level, City Of Diamonds is exactly the kind of mid-tier performer that quietly keeps racing interesting: not a superstar, but a genuine competitor with more to offer.
