In 2020, women's cricket in England was restructured, creating eight new 'regional hub' teams, with the intention of playing both 50-over and 20-over cricket. Northern Diamonds were one of the sides created under this structure, effectively replacing the Women's Cricket Super League team Yorkshire Diamonds and representing the North East and Yorkshire, partnering with Yorkshire, Durham and Northumberland. The side was to be captained by Hollie Armitage and coached by Danielle Hazell. Due to the COVID-19 pandemic, the 2020 season was truncated, and only 50-over cricket was played, in the Rachael Heyhoe Flint Trophy. Northern Diamonds won the North Group in the competition, winning five of their six matches to progress to the final. In the final, they faced Southern Vipers, who scored 231 batting first. However, Charlotte Taylor's 6/34 helped bowl out the Diamonds for 193, meaning they finished as runners-up. At the end of the season, five Diamonds players were given full-time domestic contracts, the first of their kind in England: Hollie Armitage, Beth Langston, Linsey Smith, Phoebe Graham and Jenny Gunn.

The following season, 2021, Northern Diamonds competed in both the Rachael Heyhoe Flint Trophy and the newly formed Twenty20 competition, the Charlotte Edwards Cup. In the Charlotte Edwards Cup, the side topped Group B with four wins from their six matches, just edging out Western Storm on Net Run Rate to qualify for the play-off on Finals Day. In the play-off, Diamonds beat Southern Vipers by 18 runs to qualify for the final, where they faced South East Stars. Batting first, Northern Diamonds made 138/4 with captain Armitage making 59*. However, Stars chased the target down with 2 overs to spare to win by 5 wickets. In the Rachael Heyhoe Flint Trophy, Northern Diamonds again qualified for the knockout stages, finishing second in the group with five wins from their seven matches. They faced Central Sparks in the play-off, and beat them by 6 wickets thanks to Ami Campbell's 76 to progress to the final, where they again faced Southern Vipers. Batting first in the final, the Diamonds made 183, with Campbell again top-scoring with 60. However, despite reducing Vipers to 109/7, the side went on to lose the final by 3 wickets with 2 balls to spare.

In 2022, the side finished second in their Charlotte Edwards Cup group, with three wins from their six games, missing out on qualifying for Finals Day as the worst second-placed team. The side topped the group in the Rachael Heyhoe Flint Trophy, however, going unbeaten. They faced Southern Vipers in the final, for the third consecutive time in the Rachael Heyhoe Flint Trophy, but this time emerged victorious by two runs. Diamonds batter Lauren Winfield-Hill was the leading run-scorer in the competition, and bowler Linsey Smith was the joint leading wicket-taker.

In 2023, they finished fourth out of eight in the Charlotte Edwards Cup and sixth out of eight in the Rachael Heyhoe Flint Trophy. Diamonds batter Lauren Winfield-Hill was again the leading run-scorer in the Rachael Heyhoe Flint Trophy, with 663 runs including one century.
