i also had the "fake version" of this charm. I was lucky this week to be able to purchase a authentic unicorn charm.
So i can tell the differences and i will post a few pics. But i must say next to each other.... they are both beautiful and i love them both!!!
The differences are:
1.
The details of the horse a more visible on the "fake" one. The juicy charm has a sort of clear coating over the enamel. So you can see the detail but not as clearly as on the fake charm because the fake does not have this coat over the enamel.
2. The horn of the unicorn has black lines on the fake one and not on the real one.
3. The hair of the horse neatly follow his neck on the real one. The fake one has a gap.
4. The clasp of the real one is silver and on the fake one it's gold.
5. The gold bottom of the fake one goes all the way to the edge of the bottom. On the real one there is white enamel around it on the bottom.
Here are the pictures (sorry not the best quality).
