Diamond

Diamond is the single most rarest ore that you can mine out of a Rare Ore Deposit. If you sell it, it will fetch an extremely high price - 2000 Rupees. If you collect enough Diamonds, you can go to Gerudo Town and ask the jewelry maker to turn it into a Diamond Circlet. The Diamond is also a key ingredient that you can use when you need to repair or need another Great Eagle Bow. This, 5 Bundles Of Wood and a Swallow Bow can be combined when given to Harth to repair or make another Great Eagle Bow.
