Ruby is one of four gemstones introduced in the May 20, 2016 Tradelands update. It shares similar properties to its other gem counterparts: Emerald, Amethyst, and Sapphire (Unconfirmed). Rubies, like the other gems, can only be obtained by striking loose rocks on Perth, Fenwick, Blackwind Cove and Freeport with a Golden or Gemstone Pickaxe. Because of these requirements, Rubies and the other gemstones are considered to be quite difficult to get, as their natural drop rates are quite low and locked behind tools made of the rarest materials in the game.
When used to create tools, weapons, and cannons, Rubies give them a red colored, smooth and translucent textured appearance to whatever part is affected.
Gem equipment has a 1/4 chance of losing durability upon use.
