Luigi’s Mansion 3 – B1 gem locations and how to get them

There are six collectible gems on each floor in Luigi’s Mansion 3. In this guide, I’ll show you where to find all six gems on the B1 floor and tell you how to get your hands on them. You’ll need to unlock certain abilities before you’ll be able to collect some of these gems, so you may have to come back later on in the game.

Please note that some of the gems will appear clear rather than coloured in the screenshots seen below, this is because I had already collected them during my playthrough before creating this guide.

Gem #1 – Laundry Room

You’ll find the Green Gem in the Laundry Room. It’s in the middle of the three dryers in the second part of the room. To get it, you’ll need to perform a Suction Shot (L followed by ZR + A) on the dryer door to rip it open, causing the Gem to fall out.

Gem #2 – Garage

You’ll find the Clear Gem in a cloth-covered car in the garage. To grab it, vacuum up the cloth and then use your Strobulb (hold R) on the light to open the trunk, revealing the gem.

Gem #3 – Garage

You’ll also find the Red Gem in the garage, behind the chain fence on the far left hand side of the room. To get your hands on it, use Gooigi to get through the fence, then use a Suction Shot to tear open the electrical box on the left hand side. Once you’ve done that, use your Strobulb on the green light and the gem will pop out of the machine in the background.

Gem #4 – Elevator Shaft

The Blue Gem is pretty well hidden inside the elevator shaft. To get to it, head to the northeast corner of the garage and use a Suction Shot to pull the cover off the elevator shaft. Once inside, walk round to the right and climb the ladder. Once you get up top, follow the platform around to the left and use Gooigi to go through the grate in the floor. You’ll find the gem on the right hand side of this lower platform, directly behind the ladder which you just climbed.

Gem #5 – Service Hallway

The Purple Gem is one of the easiest to find, because it’s hidden in plain sight. In the Service Hallway, just to the right of the door which leads into the Garage, you’ll see a picture of a gem on the wall. Shine your Dark Light on it (hold X) and the Gem will pop out.

Gem #6 – Service Stairwell

As you run up the stairs in the Service Stairwell you should spot the Yellow Gem directly underneath you as you reach the top. To get to it, simply use Gooigi to slip through the grate at the very top of the stairs.

And there you have it! Congratulations, you just collected all six gems.
