Luigis Mansion 3 Gems 1F Locations And Collection Guide

Collecting every gem in Luigi's Mansion 3 is one of the most satisfying achievements for completionists exploring the haunted Last Resort hotel. The First Floor Grand Lobby serves as your initial entryway into the sprawling mansion, housing six hidden gems tucked away behind clever environmental puzzles. Securing these collectibles requires a mix of fundamental suction abilities, environmental observation, and unlocking Gooigi later in the campaign.
Locating the White and Red Gems in the Main Lobby
The White Gem is hidden near the left side of the main lobby area behind a concealed wall structure. Players need to use the Dark-Light Device on the missing couch near the desk area to reveal a hidden portrait containing the gem. Vacuuming the revealed object drops the jewel directly onto the lobby floor for easy collection.
To acquire the Red Gem, navigate over to the sofa area on the right side of the first floor. Use Gooigi or Luigi to perform a Suction Shot on the carpet pattern near the desk to trigger the secret mechanism. Revealing the hidden compartment behind the receptionist counter yields the red jewel after a quick puzzle sequence.
Finding the Blue and Green Gems in Secret Spaces
The Blue Gem requires players to venture toward the far left corner of the lobby where a suspicious floor vent rests under a plant. Using Gooigi to drop down into the lower pipe network allows players to reach the elevated ledge behind the decorative wall. Pushing the gem off the ledge brings it down to the main level for Luigi to pick up.
For the Green Gem, head over to the central elevator area where a potted plant stands near a metal grate. Utilizing the Suction Shot on the plant pot breaks the obstacle and reveals an underground airflow channel. Blowing air into the grate using the Poltergust G-00 causes the green jewel to shoot upward out of the floor.
Unlocking the Purple and Yellow Gems to Complete 1F
The Purple Gem is located behind the large portrait hanging high up on the wall near the grand staircase. Players must use the Strobulb flash on the light socket near the reception desk to trigger the hidden wall mechanism. Once rotated, the portrait releases the purple gem onto the floor below.
Finally, the Yellow Gem is stored inside the glass display case situated in the lobby region of the first floor. Breaking the reinforced glass casing using a nearby prop or targeted Suction Shot shatters the barrier. Snagging this last gem completes the full set for Floor 1F and updates your collection log in the Lab.
