A simple mod. Adds a way of getting emeralds in early game. It's a tedious way, but really easy. Since emerlads barely have any use, I made this mod.
You will need 4 materials: Sand, Dirt, Stone, and Gravel.
Smelt Dirt and stone to get their ingots.
Smelt Gravel to get its gem.
Sand gem recipe:  = None [S] = Sand
