Introduction to red coral: Red coral is a polyp-type colonial animal. Its skeleton is in the form of a dendritic complex, with a dense texture and bright color. It is often used as gemstones or carving materials. The court beads of ancient Chinese emperors were made of red coral. Red corals mostly grow in shallow sea areas near the equator and in tropical and subtropical areas, where there is sufficient sunlight, which is conducive to algae photosynthesis. The picture shows precious original red coral.
