Vatican cameos are intricately carved gemstones that are often set into jewelry or other decorative items. They are typically made from semi-precious stones such as onyx, sardonyx, or agate, and feature detailed relief carvings of religious or mythological scenes. The term "Vatican cameo" is derived from the fact that many of these carvings were created in Rome during the Renaissance period, and were often associated with the Vatican and the Catholic Church. These exquisite pieces of art have been highly prized for centuries for their craftsmanship and historical significance. **
