Jeweled Apple is an item added by Tinkers' Construct. They are similar to the Golden Apple in vanilla Minecraft, in the sense that it is a food item that gives potion effects when consumed and is crafted with minerals and Apples. It bestows 1 minute of Haste, Strength, and Resistance, but unlike Vanilla's Golden Apple, it does not bestow regeneration. The item's appearance is similar to a vanilla Apple, but has the same shade of light blue a Diamond has.
The Jeweled Apple is only used in Heart Canisters.
