Make a match next to the Brooch to dislodge its tarnished Stones. Once you do, three Stones will appear on the board. Activate bonuses and make matches next to the Stones to clean them first, then return them to the Brooch. Once all three gems are back in their places, the element will disappear!

IMPORTANT:
It takes several steps to clear this element. Try to complete the Brooch at the beginning of the level to save your moves.
