Other option is acetone/Fingernail polish remover, or lighter fluid. Freezing cause contraction,you then make a space around periphery. heat causes expansion, chemical reaction of above mentioned have been used with sucess by me personally. Results may vary .
While this may work it sound risky on a treasured stone. Why not whittle away the box and then plane off the remaing wood and glue and then sandpaper. Then you can seal it. Low risk and it still gets the job done.
