There is no single answer to this question, as the meaning of a pearl necklace can vary depending on the context and individual style of the wearer. For some men, wearing a pearl necklace may be intended as a statement about their personal style or fashion preferences. For others, it could be seen as an expression of masculinity or an indication of cultural or spiritual values. Ultimately, the meaning of a pearl necklace (or any piece of jewelry) is up to the interpretation of the wearer and those who see it.
