But for accessories totally geared to gamers, there’s the Super Mario Bros. Piranha Earrings for you.

Even those who don’t really play Super Mario Bros. will be able to recognize this distinct potted and dotted plant, who’s actually a pretty bad guy in the game.

Who knew such a ferociously named villain (the “Piranha Plant”) could make such an adorable-looking earring? Just look at it taking a bite out of her ear lobe.

Unfortunately, the earrings are sold out for now and will be made available again around September 1. They’re available from Lizglizz’s Shop on Etsy, so you might want to bookmark the page for easy reference later on.

But where there’s a will, there’s a way, and that’s exactly what we have here.

These stainless steel “You Are Sooo Sharp” earrings each have a miniature knife on them, which not only folds out, but is actually a functional blade.

When closed, they measure in at 7/8″ long, and the blade itself is 9/16″ long. It’s definitely sharp enough that you don’t want to poke yourself with it. In fact, you can use these to cut paper, tape, open envelopes or pop balloons. Just don’t try and cut a New York Strip with one. You’re asking for trouble.

They are definitely dangerous. In fact, the guys over at You gNeek who sell them say you have to be 18 or older to buy a pair. Whatever you do, don’t wear these through airport security, and definitely don’t leave them open while wearing them unless you want to feel some pain.

If you’re anything like me, then you’ll also want to complement those gorgeous gamer necklaces with aptly themed earrings, like these white vintage circuit earrings that are made from an old circuit board.

I like how a lot of designers are coming up with pieces that showcase geekery at their finest and most fashionable best. You might get a couple of lot of stares from other people who see you with these earrings on. But in my opinion, they’re a really fun and fashionable way of displaying geeky side with a chic vibe.

I’m heading off to order a pair of these myself on Sparkover’s Shop on Etsy now. They’re available for $20 a pair, by the way.

You can also get a single Nuka Cola Quantum Earring ($8), if you’re a cheap bastard. But if you’re on the generous side, get the Nuka Cola Quantum Necklace ($18). It has more dirty trinkets!

If you like regular Nuka Cola, there’s also a Nuka Cola (red) necklace ($18) available. All of these items – and more, including baby Metroids in a jar – are available at Phenocryst Miniatures’ Etsy shop. Remember, even if your great-great-great-great granddaughter/son doesn’t like jewelry, the bottle caps can also be used to buy food or bullets.

This potiony pair is available right now for only $8 (USD) at Etsy. The perfect thing to buy yourself for the holidays? Maybe so. But what if you’re not necessarily a Final Fantasy fan? Fear not, friends; there are a few other things available, too–like this Legend of Zelda-inspired ocarina necklace!

The Ordinary Vanity Etsy shopfront is packed with all sorts of similar items, from Phoenix Down earrings (arguably less useful than potions, but maybe more important!) to Triforce necklaces. A few other games are represented here, too, like Kingdom Hearts. Maybe you can find a little something for everyone on your RPG gamer list.

You could get away with those almost anywhere. Does anyone really spend that much time studying your cufflinks, unless you make a point of showing them off? See, they’re subtle yet showy–in the right moments.

But there’s all kinds of stuff to be found in the store, from mainstream to the more obscure, to the absolutely adorable… and by that, I mean these moogle earrings:

If you have a semi-geeky favorite franchise, it’s likely there’s something related to it in this store.

Of course, the glory days turned into gory days when everyone started killing each other, but eh. Details! Besides, these earrings would be just as stylish at a party as they would at the massacre afterward.

The earrings are available for $28 (USD) in EstelledeParis’ Etsy shop, where there are a few other game-inspired items sprinkled among the brass jewelry and art deco crafts. Definitely an eclectic array, but sometimes, those are the best kinds of stores!

Don’t like ‘em? Etsy seller dvrdown has a pair for you, too:

Aw, that’s mean. j/k lol. Er, wait:

There, a proper LOL. Say it with beads. And at pairs of earrings for less than five bucks, you can afford to!

dvrdown has lots of different handmade earrings, from the beaded variety above to rings made from wooden buttons. It’s a charming little store, and worth a look if you like geeky or off-the-wall items.

Unfortunately, however, in order to pull this one off, you’re gonna need more than just an old keyboard. While there’s a detailed tutorial available, it might just require materials or steps that seem foreign to you. If you have a dremel tool lying around, though, or are familiar with jewelry-making, then you’re a few quick steps away from your own keyboard earrings.

What keys to choose? Your initials? Arrow keys? A two-tiered set so you can use WASD? That would require some thought.

Geeky jewelry is common, but it’s usually restricted to the realms of science fiction rather than actual science. The collection has all sorts of cellular-inspired items that you can hang about your person.

Petri dish-inspired earrings: better than wearing actual petri dishes on your ears. Trust me on this one.
