Sponge coral, also known as sea sponge coral or bamboo coral, is an organic gemstone formed from the skeletal remains of marine coral polyps. It typically has a porous, sponge-like appearance and is often dyed to enhance its color. Sponge coral comes in various shades, including red, pink, orange, and black. It is commonly used in jewelry, particularly in beadwork and cabochon settings. Fun fact: Sponge coral is not actually a true coral species but rather a type of coral known as gorgonian coral, which grows in tree-like colonies on the ocean floor. Despite its name, sponge coral is not soft like a sea sponge but has a hard calcium carbonate skeleton like other corals. In addition to its use in jewelry, sponge coral has also been utilized in traditional medicine and as a decorative material in art and sculpture throughout history.
