Finding it is not so difficult. But buying it will be the problem, since you will need many ancient components and several thousand rubies. To unlock it, go to the extreme northeast of the map, to Akkala Ancient Tech Lab, then finish "Robbie's Research" to reactivate the furnace. Once it is done, he will offer you ancient equipment craft. First of all, please note that you are not obliged to buy the helm if you have the tiara placed in a chest in the basement of Edal Island (to the north). If you decide to buy the complete set he will want: 6000 rubies, 60 ancient gears, 9 ancient hearts, 5 ancient springs, 5 ancient shafts and 5 ancient screws.
