Yikes ... code was pretty messy and didn't even pass the parse phase.
examine your camera look_at and location, also closing brace in wrong
place/missing (materials) one or two places.

After a bit of cleanup, i think the culprit is the rgbt <0,0,0,0.8> that
you had on the box (crystal) ... I changed to rgbt 1, and did a render
with ior 1.33 on ellipse (liquid) and the box with the same ior ...
bingo can't see box, then changed to ior 1.55 for the box and looks ok
fine to me.

I also changed the geometry of the items as you were using VERY VERY
small values, also didn't understand the looks_like you had for the
light source ... is this supposed to be a microscopic view of a crystal
suspended in a drop of water on a slide?
