I can't decide if the bracelets are the same ones worn by Raja Zarith Sofiah for her husband's coronation in 2015 with the sapphires replaced by yellow diamonds. When I look at the picture on the left I think they are different but when I look at the picture on the right I think they are the same.
The sapphire bracelets are part of the crown jewels of Johor so I would imagine that the the sapphires were only replaced temporarily if they are the same.
