Or does stone have its own ways of finding age of carving that is independent of nearby organic material?First of all, carbon dating is a highly inexact science to begin with.

Sedimentary rocks may be carbon-dated by inference if they contain carbonaceous fossils.
The same may be true for igneous rocks, but finding suitable carbon samples may be unlikely.
They would assume that today's utensil is older than the one from 1000 years ago, on the basis of handiwork.
So is the part about the carbon dating of nearby organic material true?
Radiometric dating has been used to determine the ages of the Earth, Moon, meteorites, ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and many of other geological events and processes.

When living things die, they stop taking in carbon-14, and the radioactive clock is "set"!
Any dead material incorporated with sedimentary deposits is a possible candidate for carbon-14 dating.
If you submit identical samples to different labs you will get widely differing results.
Also, all labs I know of require the submission to describe where the sample came from and provide an estimated age of the sample.
A limitation of true "carbon dating" is that it is not very accurate at all for times less than several thousands of years.
