Ceramic glazed coral is a kind of art and decorative material, which is mainly used to make jewelry, hand ornaments, pendants and so on. Because of its unique texture and color, it cannot be completely replaced by other materials. However, if you want to find a similar substitute, you can consider the following materials:

1. Coral stone: Coral stone is a natural mineral with similar texture and color to coral. It can be used to make jewelry and decorations, and is a common substitute.

2. Pearl: Pearl is a shiny and beautiful organic material, which can be used to make decorations similar to coral colored glaze coral. It has unique texture and luster and is a good substitute material.

3. Plastic or resin: If you only pursue similar appearance and don't care about the nature of the material, you can consider using plastic or resin as a substitute for coral glazed coral. These materials can imitate the appearance and texture of coral.

Please note that although these materials can similarly simulate the appearance of coral glazed corals, they cannot completely replace the unique characteristics of real coral glazed corals. In addition, when purchasing or using coral products, please ensure compliance with relevant laws and regulations to protect coral resources and the environment.
