"A large precious stone."
The Ruby (ルビー Rubī ) is a treasure item that can be found in Resident Evil 4.
As a treasure item, its only purpose is as a source of income to pay for new items and weapon upgrades from the Merchant. They can be sold at the merchant for 10,000₧, making them worthwhile to obtain.
