What minerals should I sell?

[Loko8]

So I've been selling all my quartz and now it turns out I need it for the high quality sprinkler. I have many other valuables that I don't know if I should sell or if I'll need them for a crafting recipe in the future.

Amethysts, topaz, rubies etc.

Minerals that have an use shouldn't be sold, like quartz or earth crystalz.
You can check the wiki for their uses n stuff.

I keep almost all my earth crystals, fire and regular quartz, aquamarine, frozen tears (married seb so the more the better) and marble for recipes and at least 5 of each: topaz, rubies, amethyst, jade, diamonds, tiger eyes, and emeralds for gifts and quests... everything else can be sold.... and if youre lucky keep any prismatic shards they are great for gifts, grange display, and a secret in the game :D but are also very valuable if you get multiples (only been that lucky in one of my games)

Marble is only important if you're going for the craft everything achievement, but the same can be said about most things.

The real frustration is that there are more update(s) coming which could utilize who knows what. I feel obliged to hoard everything.
