Who were the first to wear pearls as jewelry?”
From pearloasis.com: “Since ancient times, the pearl has been a symbol of unblemished perfection. It is the oldest known gem, and for centuries it was considered the most valuable. A fragment of the oldest known pearl jewelry, found in the sarcophagus of a Persian princess who died in 520 BC, is displayed in the Louvre in Paris.

The Latin word for pearl literally means “unique”, attesting to the fact that no two pearls are identical.” It’s worth reading the page in full – very interesting.
