The three central diamonds on the ring remained unchanged, but the plain gold band was upgraded to a diamond eternity band. 

No statement was made by the royal couple at the time, but it’s said that she changed it to match an eternity band Prince Harry gifted her upon the birth of their son Archie.

The eternity band Meghan was gifted was also designed by Harry alongside jeweller Lorraine Schwartz. 

It is said to incorporate their growing family in the form of Meghan, Harry, Archie and later Lilibet’s birthstones.
