Ring of wealth

A Ring of Wealth can be made by enchanting a Dragonstone ring with the spell Enchant Level 5 Jewellery, which takes a Magic level of 68 to cast. The Ring of wealth increases the chance of its wearer getting rare or good item drops from monster drops.

While Jagex does not often give out details, it was stated in one issue of the God Letters called Guthix Ponders that monster drops are determined by a random spin on a "wheel". When you kill a monster, it rolls the first "wheel." If it lands on "rare item," it rolls another wheel that determines what rare item it will be. The Ring of wealth increases the chance of getting a better (more valuable) rare. For example, if a monster drops a Bronze platebody and a Steel sword and the Ring of wealth is equipped, then it would most likely be the Steel sword.

Trivia

 * The Ring of wealth does not increase the chance of getting a clue scroll from any monster (this has been confirmed multiple times), and it does not increase the chance of getting a more valuable item at the end of the Treasure Trail or from the Barrows minigame.
 * Contrary to popular belief, the Ring of Wealth does NOT affect drops while LootShare is on.[1] The chances of getting a drop increases every time someone else in a clan gets a drop.
 * It is not known if it increases the drop rate of a Draconic visage.
 * There have been reports that the ring of wealth increases the chance of better PvP drops, but this has not yet been confirmed.
