In the material editor choose a bright color(white) for both the high light and the reflective light. Also might want to give the ambient light something besides black. Not to bright on the ambient though as it can bleach the details right out. In the right situation however abient light can add a little luster to the material. ALso you might want to add a reflection map and turn the strength down. Hope this helps
