Hi there, fellow earthlings. It struck me earlier today (indeed, more than 40 minutes earlier than now (now as in, now when I write this, not when you read it (duh))), while watching a picture of a mineral (Olivine), that minerals should really be categorised based on if they look like candy or not.

After looking at a lot of pictures, I realised that this wouldn't be very realistic, because a single kind of mineral can look very different based on stuff (traces of stuff, and stuff, ask a chemistry fellow or a geologist or something like that for details). So instead, the criterion should be something like Minerals that (can)? look (tasty|like candy). I'm pretty sure you agree.

The following is a list of minerals I found to fit Minerals that (can)? look (tasty|like candy) (in no particular order, really):

Olivine - Don't mistake for olives. Looks like candy.
Biotite - Mmmm, liquorice, anyone?
Emerald - The potential of looking like candy is there, and it can obviously look tasty.
Jadeite - Now available as candy buttons in different sizes.
Chrysoberyl - Assorted, rough throat lozenges for everyone.
Amber - OK, so the insects doesn't look that tasty, but there is candy with insects in it very much like so. And except the insects, it does look tasty.
Cordierite - Dunno what to say about this. It looks a bit candyish.
Citrine - The fresh lemon flavour.
Spinel - Yes, candy can look like that. I've seen candy very similar to it.
Gold - Come on, everyone thinks gold to be tasty. You just want to lick it. Or at least grab it and run for it.
Gypsum - Well, maybe not really candy. More like some kind of potato snack that has been treated incorrectly.
Halite - Reminds me of sugar, the white gold. As we all know: First you get the sugar, then you get the power, then you get the women - Homer J. Simpson (I demand this to be considered fair use).
Garnet - Very tasty.
Euclase - Possibly sugarish.
Leucite - Those could very well be candy (the article also mentions that leucite rocks).
Magnetite - Mmmm, more liquorice.
Phlogopite - Yes, maybe.
Prehnite - Looks very tasty, very fresh, and very tasty. Tasty.
Rhodochrosite - Artificial colouring? Not needed.
Rhodonite - Last one looks very similar to a kind of candy that I've really eaten. Dunno its name, but it's liquorice and something.
Ruby - Sweet.
Selenite - Sugarish again? Looks a bit fresher, though. For that extra minty breath?
Smithsonite - Actually, I'm not sure about this one. And the name sounds mysteriously religous.
Xenotime - It's xeno time!
Sapphire - Ho ho ho, merry sapphires.
Milk quartz - Could be tasty.
Rose quartz - One very tasty elephant!
Tanzanite - Yes.
Uvarovite - Mashed jelly, yes?
Zincite - Obviously looks very candy like in one of the pictures.
Bixbite - Very red, at least. But a bit low quality, so the accuracy is low.
Lepidolite - Some candy are weird.
Manganotantalite - Part of it looks both tasty and like candy.
Diamond - While not looking like candy (some things about it are dead giveaways), I say it's tasty, much like gold. Grab and run!
Calcite - Sugar mutant ninja mineral.
Spodumene - Has some candy qualities.

And that's all I found that I could include with a straight face. But here's three bonus minerals:
Cinnabar - Some kind of bad/weird kind of meatish thing.
Thulite - Also meatish. Let's fry it!
Skutterudite - Funny name ^_^

That's all folks. And remember, mineralogy, or even geology or at least geochemistry, can be fun if approached from the right direction.
