1. Because then I'd be a heckin' unicorn!

2. If/when I got into magical mischief, it's important that I'm still light on my feet. A massive magical gem in my chest would weigh me down as I tried to make a get away so I've got to opt for the fancy head horn. Also, I might be able to fence a narwhal if desired.

3. Simple, it doubles as a defensive weapon, meat/vegetable skewer, lock pick, spousal back scratcher, and so many other things.

The chest gem just makes you look like a “My Little Pony” version of Ironman or Battle Beasts.

4. Because I would look like a unicorn, and what girl hasn't dreamed of that since she was a little girl. AND, it can be used as a defense weapon if ever you ever find yourself in need. But mostly because it'd be cute.

1. You can't wear a hat with a unicorn horn. You can still wear a sweater with a giant crystal gem in your chest.

2. Easier to hide so I don't quickly reveal my powers to my nemesis!

3. This is difficult but I'm swayed by the practicality aspect. A horn on your head would simply get in the way all the time - boarding a plane would be a nightmare. A magical gem would be cool af and i could go everywhere shirtless (with toned body I got by magic obviously!)

4. Belly button powers!

5. I would look like Ironman!!

6. If my life turns to the worst, I could always sell the gem and become a regular human again. Regular human who is now LOADED. hehe.
