Hello Julien:
First idea: If you have access to a sensitive balance and the material
from which the rosette is made, weigh a circle of the uncut material
the same diameter as the rosette and compare it to the weight of the
finished rosette. That would give a good approximation of the voids. It
would be more accurate if the rosette were weighed before any purely
decorative carving was done.
Second idea: It should be possible to rig up a light box with a
photographic light meter to measure the amount of light passing through
the rosette (unless the rosette material itself transmits light).
