Luigi’s Mansion 3: How To Get All Gems On Each Floor | B1, 1F & 2F Locations Guide

There are 6 gems on each floor in Luigi’s Mansion 3, and finding them all is a difficult challenge. They’re extremely well-hidden, and many of them require out-of-the-box thinking to uncover. Here you’ll find all the gem locations for the first three floors of the game, and learn a little bit about how to actually start unlocking these things. Even if you search each floor thoroughly, it’s easy to miss most of the gems.

In these early floors, you won’t have access to all the abilities you need. You’ll need to have Gooigi to unlock certain gems. Gooigi is a green goop clone that you can control independently of Luigi. He can do everything Luigi can do — except step in water. You’ll need him to give a little extra oomph to your attacks, and with Gooigi’s help, it’s possible to clear out your collectibles in B1, 1F, and 2F. Let’s get started.
