“Gloucester-Hartpury has been such an important part of my rugby journey and a true Holm for the last seven years,” said Jones, who has won 57 caps at hooker.
“I’ve experienced some of my highest highs and lowest lows here, and there’s no other group I would have wanted by my side through it all.
“Together, we’ve shared incredible moments, winning titles, creating lifelong memories, and building friendships that will last forever. It has been a privilege to run out and share a pitch with so many amazing people over the years.
“While this marks the end of an era, I will always be proud to have worn the Cherry & White shirt and played a small part in the legacy we’ve built for the generations of girls to come.”
Wales back row Lewis said leaving Gloucester-Hartpury is “incredibly difficult” with the club playing such a big part of her life on and off the pitch.
“I’ve spent the best years of my rugby journey here, surrounded by awesome team mates, coaches and staff who have pushed me to become a better player and person every day,” said the 65-capped international.
“To have played a small part of the success we’ve achieved together is something I’ll always be proud of, these are moments I will cherish forever.
“Gloucester-Hartpury will always hold a special place in my heart. It’s time for me to leave The Circus and embrace a new challenge.”
Discussing the capture of Lewis, Bears head coach Scott Lawson said: “Bethan is a consistent performer at both club and international level and her experience, leadership and competitiveness will be hugely valuable to our squad.”
