Gemstone Walls are background walls crafted from Gemstone Blocks at a Work Bench in a Graveyard mini-biome, or found naturally-generated in the world. Naturally-generated Gemstone Walls can be found in Gemstone Caves in the Underground and Cavern layers. They can be destroyed with a hammer, but they will drop nothing, will not stop enemies from spawning, and are not valid for houses. However, crafted Gemstone Walls can be used for valid housing, and will drop if freed with a hammer.
- Despite Gemstone Blocks selling for 5, Gemstone Walls have no value.
