Answer Details

The figure of speech used in "a heart of stone" is a metaphor. A metaphor is a figure of speech that compares two things by saying one thing is another thing. In this case, the speaker is comparing the person they were speaking to (whose heart is not moved by their words) to a heart of stone. This comparison helps to emphasize how unfeeling and unresponsive the person is, and how the speaker's words have had no effect on them.
