Brooches contain three heart-shaped jewels and require several actions to be eliminated. First, remove the jewels by making a match next to the brooch. Jewels will land in three separate tiles. Clean the jewel by making matches or activating boosters, and then make another match to put it back in place. Once all three jewels are placed back on the brooch, it will disappear from the filed.

NOTE:
Brooches require a lot of moves to be eliminated, so try collecting them first to save moves.
