10F — Tomb Suites — All Six Gems — Luigi’s Mansion 3

Luigi's Mansion 3 guide hub

Find all six gems in 10F — Tomb Suites. The colours are white, red, blue, green, purple and yellow. Gem collection is separate from the ending money rank; completing all seventeen floor sets unlocks Suction Shot Type-C.

Required tools and return visits

Unlock Gooigi and the Dark-Light Device before completing the floor. Clear the story route first if a door or room mechanism remains locked.

White gem — Central Chamber — nested sarcophagi

Open the sarcophagus beside the east door with Suction Shot. Keep opening the smaller containers inside it until a crystal ghost appears. Capture it.

Red gem — Elevator Hall — snake tail

Pull the snake statue’s tail with one character. Keep it held while switching to the other, then vacuum the red gem from the open mouth.

Blue gem — Jewel Chamber — extra cross

Finish the poison-room puzzle first. Break the pot left of the rear statue and collect its cross-shaped jewel. Fire it into the matching socket on the left wall near the entrance for the blue gem.

Green gem — Scale Chamber — floor drain

After finishing the weight puzzle, vacuum the sand from the left side of the room. Send Gooigi down the uncovered drain and open the chest below.

Purple gem — Sandy Grand Hall — west dune

Vacuum the sand west of the pyramid, roughly level with its lower-left corner. Clear the dune until the purple gem is exposed.

Yellow gem — Sandy Grand Hall — broken snake

Clear the southeast sand around the stone snake. Restore both missing sections with Dark-Light, including the middle and tail. Collect the gem from its opened mouth.

Six-gem check

Open the floor collection screen and check all six colour slots. A missing colour identifies the exact entry to revisit above. Gem ghosts must be fully captured before their gem is awarded.
