Hmm..... Nicely pointed out.
Nayru's Love (
OoT)
Magic Armour (WW)
Din's Fire (
OoT)
It is the same shape as Nayru's love, however the colors resemble Din's Fire moreso. They do serve the same purpose, yet depict different colours and have different names
It could become a complicated issue of where it is obtained in game on the timline (Child or adult). Also it is a fairy possession, so Zunari would probably have to obtain it from a fairy.
I personally doubt they are the same artifact... but they may be.
