Year 5-6 I went to the mine for 145 days without stopping and here is the result:

I cloned the diamonds in the crystal stores, I farmed a little Iridium bars, but there are so few of them that I honestly got tired of doing that, Iridium is easier with bombs, stone ladders and lucky food, the prismatic crystals are the combination of the six years I never sold a single one of which I started the game and the rest of the time I spent fishing, something I like to do.
