There are 6 colored Gemstones to find on each
floor in Luigi’s Mansion 3. This guide will show where to find all of them on the 13th
floor. The White Gem can be found in the office room
to the left of the elevator. Use the Strobulb to make a bell appear on the the desk and
ring it. Nothing will happen but when you go to leave, you’ll hear a simple pattern
of rings. Go back to the bell and ring it in the same way to have the gem ghost appear.
Defeat it to claim the gem. The Red Gem is located in the weight room.
Go to the scale at the back right corner and stand on it. In the mirror, you should see
a panel open containing the gem. Use Gooigi to retrieve it. To find the Blue Gem, head down the stairs
in the locker room and grab one of the boxing gloves. Launch it at the sign for the pool
to break it and reveal the gem. The Green Gem is in the shower room. After
all the showers have been turned off, send Gooigi down the grate. Below there’s a wheel
that can be turned with the Poltergust. Turn it all the way to the left to drain the water.
On the right side, you’ll find the gem. The Purple Gem is one we’re a little unclear
on, but what we believe the process is involves the telephone in the elevator room. The person
on the other end will mention channel 3 and there happens to be radio in this room. We
turned to channel 3 and while the lights changed, no ghosts appeared. After defeating the boss,
we returned to this room where a gem ghost and two treasure ghosts were exercising on
the treadmills. Defeat it to receive the gem. The Yellow Gem is in the elevator room. When
stepping on the central circle, it’ll lower while raising the glass on the right. Summon
Gooigi on it to have the circle drop further and open the glass the entire way, freeing
the gem. And that’s all the gemstone locations on
Floor 13! Thanks for watching and be sure to subscribe to GameXplain for more on Luigi’s
