I'm not entirely sure but It looks like red tourmaline.

garnet = a group of minerals; see almandine, andradite, grossular, spessartine, uvarovite
http://www.maine.gov/dacf/mgs/explore/minerals/guide/chapter...
"For gem identification purposes, a pick-up response to a strong neodymium magnet separates garnet from all other natural transparent gemstones
commonly used in the jewelry trade."

I agree with Morgan, it's most likely a garnet (pyrop or almandine I think..).

I thought it was almandine, but I didn't know if it could be as light as my rock, thanks for the help everyone!

It does have the right structure for garnet and is probably almandine rather than pyrope (which tends to have a more claret colour red) the reason
your rock is not as heavy as you expect for garnet is that it is actually granitic material with little garnets that hardly contribute to the density
of the whole specimen.
