Jewel piece

A Jewel Piece, also referred to as a Gem Piece,  is an object in the Game Boy Advance game Wario Land 4. Four Jewel Pieces can be found in each level, inside of a Jewel Piece Box. When four are joined together, it creates a jewel. Wario does not need to find all the Jewel Pieces to go on to the next level, but he does need to find them all in order to battle the area's boss. The color of the Jewel Piece is dependent on the passage Wario is in.

Four purple Jewel Pieces appear in Hall of Hieroglyphs and four golden Jewel Pieces appear in the Golden Passage.
