FAO Quartz

FAO Quartz was a new age crystal store in Springfield.

History
When Marge was looking for a cure for Bart's ADD medication side effects, she went to FAO Quartz as she had tried everything else. The new age clerk who owned the store sold Marge healing crystals to help Bart. Eventually, the new age clerk got a space in a local cult and joined them instead, shutting down the store and giving her entire inventory to Marge, who then set up her own store, Murmur.

Behind the Laughter
The name FAO Quartz is a reference to the toy store.
