Chef Martin's Fiancée Flaunts Huge Diamond Ring

TV chef James Martin's partner, Kim Johnson, recently showcased an impressive diamond engagement ring at the TV Choice Awards. The ring, a classic trilogy style with round brilliant-cut diamonds set in platinum, is estimated to be worth approximately £500,000. It features a central diamond of 4.0-5.0cts and two side diamonds of 3.0-3.5cts each.

Jewellery designer Jessica Flinn-Allen notes that trilogy rings traditionally represent a couple's past, present, and future. This style offers a blend of contemporary design with a nod to Victorian vintage aesthetics, suiting Johnson perfectly and indicating thoughtfulness from Martin. The couple, who began dating after Martin's split from his previous girlfriend of 12 years, reportedly became engaged over Christmas.

Interestingly, Martin has previously voiced skepticism about marriage, stating in 2019 that it did not interest him, citing his extensive experience catering weddings. Meanwhile, Johnson was previously married to businessman Arun Nayar, from whom she divorced in 2017. She is understood to have moved in with Martin in Hampshire in October 2025.
