This question already has an answer here:

I am making an illustration in Cycles Render of a table with a lamp and a Magic-8 ball below it.

Here's what it looks like when I render:

enter image description here

On closer look, the reflection in the ball is wrong given the curvy object it is reflecting:

(image above is the result of 1000 preview samples).

Here are a couple more view of the scene and its data:

The black ball's material

enter image description here

The lamp's material

enter image description here

Another light source is present.

enter image description here

What the lamp really looks like (y'know, IKEA).

I have tried full global illumination in the render settings, various sub surf modifiers to the lamp and to the ball, Multiple Importance on and off, but this didn't change a thing.

    $\begingroup$ I think it's not the fault of IKEA lamp (though I'm not a big fan of their designs BTW ;)).It's rather the fact your sphere is not smoothed (Tool Shelf-->Tools-->Shading-Smooth). Oh, and you may give your sphere a Subsurf modifier first. $\endgroup$ – Paul Gonet Nov 22 '15 at 2:19

    $\begingroup$ @Gonzou is right, you should turn on smooth shading on your sphere. Smooth shading smooths the normals across flat faces creating the illusion of curvature. It also wouldn't hurt to add a subsurf modifier too. $\endgroup$ – PGmath Nov 22 '15 at 2:47
  • $\begingroup$ @Gonzou thanks, friend! Looks like an answer rather than a comment, feel free to magically transform it to an answer $\endgroup$ – MicroMachine Nov 22 '15 at 8:01
  • $\begingroup$ Oh, yeah, it's a duplicate, you're right! I looked for it for a while though... Should I delete it? $\endgroup$ – MicroMachine Nov 22 '15 at 22:04
