This is what my model looks like in the program at 32 samples.
This is what it looks like at 256 samples when rendering.
I tried setting everything to shade smooth (which it already was), but the seams do not dissappear. The crystals inside the liquid are yellow, however it seems that in the Final Render they somehow emit their colour to such an extent that everything becomes greenish and murky. The same issue persists if the Final Render has the same amount of samples as the viewport.
Let me know what the best way to share the .blend file is if you want it.
