Trivia: What type of jewelry comes from a living organism?
Correct Answer: Pearl
So why is this answer correct? : Pearls are one of the most enduring jewelry trends of all time, found on the necklaces of Hollywood stars and the crowns of royalty. While all mollusks can technically make pearls, only a few kinds — saltwater clams and freshwater mussels — can make gem-grade pearls. The exclusivity of authentic, high-quality pearls also contributes to their high price tag.
