Got inspired by this and tried this on many maps (currently at the same level as you 141) on fatal difficulty (no crystal totems used). And very surprisingly in 20 mins time slime fields gave the best results at 87k gems, Amcient fortress gave around 50-60 ish gems (i supposed my clear speed is still slow at fatal difficulty thats why it gave lower results).
