Jade can be tough to identify; there are lots of things that look exactly like it. Strong suspicion is often warranted. Firstly, did you find the rock in a known jade-producing area? That's a good sign. Second and thirdly, jade is hard, and very tough, a hammer is going to bounce right off it. Lastly, the best way to positively identify jade or any other gem is by consulting an expert. Find a local gem and mineral club, or a museum, or a university earth science department. Or, as a last resort, if you have none of the above, try to find a competent gemologist.
Take it to a local jeweler whom you trust.
