Other forms: lapidaries
The word lapidary relates to precious stones, especially the things people do with them such as cut, polish, and set them in a fancy bracelet.
If you know someone who carves gems, engraves marble, or does other work with precious stones, then you know someone who does lapidary work. A lot of lapidary work involves making jewelry, but doing inscriptions in monuments is also lapidary. Someone who collects precious or rare stones has a lapidary hobby. You can also call a person who works with such stones a lapidary. Lapidary comes from the Latin word, lapis, for stone.
