Coral is a naturally occurring organic gemstone that is formed by tiny marine animals called coral polyps. The hard, exoskeleton of these polyps builds up over time, creating coral reefs that can be hundreds or thousands of years old. The color of coral ranges from white and pink to red, orange, and even black, with the most prized specimens being a deep, rich red color. Coral has been used for thousands of years in jewelry making and decorative arts, prized for its natural beauty and unique patterns. However, due to overharvesting and environmental concerns, many countries have put restrictions on the sale and trade of coral.
