We find the red coral in deep depths in Mediterranean but its excavation is not allowed. We also meet corals in the Indian Ocean, in the sea of Southern China, in the Pacific Ocean and particular at northeastern Australia in the Coral Sea, where the colour of coral is lighter than the Mediterranean one.
When the coral dies, the market is used to call it apple coral or root of coral. The dead coral is durable in use, good in touch, with red shading.
