  In theory the diamond should collect photons as any other object in
the scene. It's just that photons seldom show any effect on transparent
objects and so it's an optimization to turn photon collection off for
the transparent object (less memory usage and faster rendering).
  There are, however, cases where photons *do* show some effect in the
refracting object itself (for example when it's only partially transparent).
You'll have to test which looks better.

  'collect off' does not affect reflection and refraction of light. It just
tells that photons should not be stored at the surface of the object for
lighting calculation.
