Lost Your Marbles Stoneworks is a sculpting and masonry business in Ponyville. It is a relatively recent establishment, having been founded by Dirty Rocklander a few days after her arrival.


The Stoneworks building is made of marble and held up with pillars in a manner resembling Grecolt-Romane archtecture. Internally, it consists of a display area in front where completed statues are placed, a work area, and a storage area in the back for spare materials.


The Stoneworks is in the mountains near Ponyville. It is a convenient position for Dirty to gather raw materials to work with, but going to and from it is an annoyingly long walk.
