Diamond(Advanced, Kimberlite ore) - 28.8K/m - Late Game
NOTE - If it says that objects are colliding, then press shift+enter and build the conveyer belts(from sprayer to splitter) manually.
This is a slightly modified blueprint of Yosef1313's Titanium Ingot 28.8k/pm blueprint. MK3 proliferators are fed externally by MK1 depot and logistic bots. Kimberlite ore needs to be fed locally for best output.
