Hi!
1) From left to right: Stone, iron, bronze, gold, platinum (not that it is made of these metals, but the appearance and performance of the tool would follow this classification).
Then there are the special diamonds, ice, fire, purple that can be plasma or pure magic / elemental energy and lastly the divine or epic (the dark with jewels).
2) Do you talk about a grass pick, vegetable type? Specify how she wants me to do it and post it there.
3)
