Operational service

Diamond was commissioned in a traditional ceremony on 6 May 2011 in her home port of Portsmouth. The ceremony was attended by the ship's sponsor and the Commander-in-Chief Fleet Admiral Sir Trevor Soar. Diamond continued undergoing sea trials until she entered operational service in July 2011 after the completion of her trials. The ship conducted operational training before commencing her first overseas deployment. Diamond commenced her deployment in the summer of 2012, starting with celebrations to mark the Diamond Jubilee of Her Majesty Queen Elizabeth II.

Diamond was in the Middle East Area of Operations in 2012. During Operation Recsyr in February 2014 she escorted  carrying chemical agents from Syria.

On 8 May 2017, Diamond performed a demonstration firing of an Aster 30 off the coast of Scotland.

On 4 September 2017, Diamond sailed for a 9-month deployment to the Middle East, initially scheduled to relieve HMS Monmouth, she was instead diverted to take over as flagship of Standing NATO Maritime Group 2 from sister HMS Duncan when her intended relief, HMS Ocean was redeployed to provide relief to British Overseas Territories in the Caribbean in the wake of Hurricane Irma. Diamond was relieved of her NATO duties upon the return of Ocean from the Caribbean on 30 October and resumed her planned deployment to relieve Monmouth. However, on 23 November, The Times reported that Diamond was being forced to abandon her deployment and return to Portsmouth early due to mechanical issues, which was later confirmed by the Ministry of Defence.

On 10 April 2021, Diamond left Portsmouth to conduct a 41-gun salute after the passing of His Royal Highness Prince Philip, the Duke of Edinburgh. The ship flew her ensign at half-mast.

In 2021, the ship initially deployed to the Far East as part of the UK carrier strike group centred on . However, she was compelled to detach from the group for repair in July due to reported "technical issues" likely linked to longstanding power and propulsion reliability issues with ships of the class. It was later reported that the ship had "suffered a failure of one of her gas turbines". Repairs were undertaken in Taranto, Italy and at the end of August Diamond returned to sea to rejoin the group. In mid-October 2021, after rejoining the strike group, the destroyer again experienced "technical issues", however this time reportedly not related to her propulsion system and was a decision was made to put into Singapore to have them addressed.
