This is Celestia`€™s sword, from a series I did involving semi-anthro interpretations of MLP characters. She'€ has used it in a couple of shots. It is over-the-top and gaudy, but as the weapon of a god-princess, it's meant to be. :)

I'm not marking this as fan art simply because it is an original design. The only connection to MLP is me asking myself "If this character were human and had a sword, what might it look like?"

The materials are all CC-0, but to give credit anyway, this blend uses:
Blue Metal Hexagon Tile Material http://www.blendswap.com/blends/view/77088
Gold Material for Cycles http://www.blendswap.com/blends/view/38983
Cycles Wood Material http://www.blendswap.com/blends/view/68707

HDRI world background not included, so you'll want to throw your own in there.
