According to Baidu Aigou, bone carvings and coral bones are very beautiful works of art, but the materials and production methods are different. Bone carvings are made of animal bones, and coral bones are made of natural corals. Coral bone material is 99.6% the same as human bone, which can meet the requirements of bone support, has strong stability and will not degrade. Therefore, coral bones are more suitable for medical fields, such as orthopedic surgery and dental surgery. As for which one looks better, it depends on personal preference. If you like natural materials and handicrafts, then you may prefer bone carving. If you like more modern materials and medical applications, then you may prefer coral bones.

Coral is the shell secreted by coral polyps, and its chemical composition is mainly CaCO3, which exists in the form of microcrystalline calcite aggregate with a certain amount of organic matter. Corals are mostly dendritic, with vertical stripes on them, often white in color, with a little blue and black. Coral not only looks like branches, but also has bright and beautiful colors, which can be used as decorations and has high medicinal value.
