Luigi’s Mansion: Dark Moon Guide – Gems Location Guide

Luigi’s Mansion: Dark Moon is full of crazy ghosts, money, secrets and a ton of other fun stuff to find. The main collectible in the game is called the gemstones. This Luigi’s Mansion: Dark Moon Gems Location Guide will go over how to collect all of these pieces. This is a work in progress and I will be adding the pieces as I play through the missions. If you find a piece to go along with the guide, or need some help finding a piece already listed, hit us up in the comments below. Now let’s hum along with Luigi and find all of these fragments!

Luigi's Mansion Rafters Gem
This gem can be found at the end of mission A-5. Right at the end on the third floor there is a room called Rafters that you can get in through a set of stairs. Towards the end of the level at the last spider web there is a painting , some armor on the ground, and a spider web that you have to suck up.

The gem in the West Garden is a couple step process.
