Without seeing the rock it is somewhat hard to tell but I suspect that, almost certainly, your rock is Specular Hematite. If it's rather heavy for it's size and the sparkle that you see looks like it's coming from zillions of individual specks on the surface, then it probably is Specular Hematite. Also, do the "sparklies" fall off if you rub the rock with your fingers? If they look like thin little flakes then it's certain the rock is Specular Hematite (also called Specularite).
hope this helped,
