Dear Ethel:
Of course, both your marble coffee table top and your granite top can be successfully repaired, but it is not certainly a DIY project, I can tell you that.
Special and hard-to-get epoxy glue is involved, as well as proper rodding for reinforcement and, last but not least, the resurfacing of the face of the stone around the crack to make it blend in with the rest.
Your only option is to hire s proficient stone restoration contractor in your neck of the woods.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
